Refutation of Unfalsifiable Conjectures

Authors: Colin James III
Comments: Pages.

In bivalent mathematical logic, the unfalsifiable conjecture is not contradictory, and hence tautologous to be a theorem. The theorem by definition is not contradictory, tautologous, and hence unfalsifiable. There is no distinction between the states of unfalsifiable or confirmable as opposed to falsifiable or refutable.

Unfalsifiable Conjectures in Mathematics

Authors: Craig Alan Feinstein
Comments: Progress in Physics, 2018 (vol. 14), issue 4, pages 213-214

It is generally accepted among scientists that an unfalsifiable theory, a theory which can never conceivably be proven false, can never have any use in science. In this paper, we shall address the question, “Can an unfalsifiable conjecture ever have any use in mathematics?”

Adjacency Matrices of Some Directional Paths and Stars

Authors: Rajesh Kumar T.J, Mathew Varkey T.K
Comments: 7 Pages.

Graph labeling where vertices and edges are assigned values subject to certain conditions have been motivated by various applied mathematical fields. Most of the problems in graph labeling are discussed on undirected graphs. Bloom G.S. and Hsu D.F. defined the labeling on directed graphs. In this paper, we discuss the adjacency matrices of graceful digraphs such as unidirectional paths,alternating paths,many orientations of directed star and a class of directed bistar. We also discuss the adjacency matrices of unidirectional paths and alternating paths if they are odd digraceful.

Comments: 11 Pages.

This paper introduces equal degree graphs of simple existed graphs. These graphs exhibited some properties which are co-related with the older one. We characterize graphs for which their equal degree graphs are connected, completed, disconnected but not totally disconnected. We also obtain several properties of equal degree graphs and specify which graphs are isomorphic to equal degree graphs and complement of equal degree graphs. Furthermore, the relation between equal degree graphs and degree Prime graphs is determined.

Simulation of Nontrivial Zero of Riemann Zeta Function Ver.2

Authors: Toshiro Takami
Comments: 4 Pages.

Simulation of the nontrivial zero of Riemann's prediction succeeded in mimicking with rotational force alone. Although it is a simulation with only the rotational force, it is a very approximate value because the initial value was set as the first nonzero point of the Riemann zeta function. We adopted a method of placing a rotating force on the previous value and stacking it. I could reproduce how the dragon climbs up the x = 0.5 axis. In 1.0 of the interval of the nuclear energy, simulation did not hold and it was forced to take the value of 1.1. At first, although it is out of the nonobvious point of Riemann's prediction, it gradually becomes an approximate value. However, this may also be lower than the previous value, and it should be improved in the future.

Authors: Chaitali Kar, Bappa Mondal, Tapan Kumar Roy
Comments: 17 Pages.

In this paper, an inventory model is developed without shortages where the production cost is inversely related to the set up cost and production quantity. In addition, the holding cost is considered time dependent. Here impreciseness is introduced in the storage area. The objective and constraint functions are defined by the truth (membership) degree, indeterminacy (hesitation) degree and falsity (non-membership) degree. Likewise, a non-linear programming problem with a constraint is also considered.

To overcome the shortcomings of the paper, we further modify the VIKOR strategy by incorporating compromise solution in neutrosophic cubic set environment. Finally, we solve an MAGDM problem using the modified NC-VIKOR strategy to show the feasibility, applicability and effectiveness of the proposed strategy. Further, we present sensitivity analysis to show the impact of different values of the decision making mechanism coefficient on ranking order of the alternatives.

In this paper, we propose a new technique for the enhancing images. It will work on removing the noise contained in the image as well as improving its contrast based on three different enhancing transforms, we commence by embedding the image into a neutrosophic domain; where the image will be mapped in three different levels, a level of trueness, a level of falseness and a level of indeterminacy. Hence, we act separately on each level using the enhancement transforms. Finally, we introduce a new analysis in the field of analysis and processing of images using the neutrosophic crisp set theory via Mat lab program where has been obtained three images, which helps in a new analysis to improve and retrieve images.

Fast Method of Factoring Decomposition of Rsa Cipher Vol.0

Authors: Toshiro Takami
Comments: 11 Pages.

We found that prime numbers repeat every 30, and all prime numbers are represented by 30 m + n (positive integer including m is 0, n is a prime number smaller than 30 excluding 2 and 5). If the end of the multiplication of the giant prime and the giant prime here is 5, it can be seen that any of the ends of each gigantic prime is 5. In other words, the one multiplied by a huge prime number and a huge prime number, (30 m + n) * (30 s + t) = 900 ms + 30 (mt + ns) + nt (positive integer including s is 0, t is a prime number smaller than 30 excluding 2 and 5) . nt includes something that is not a prime number. 33, 63, 93 and so on. For example 1976869607 = 27109 * 72923 (both primes 27109 and 72923) , But this factorization is unknown to third parties. 1976869607 is a 10 digit integer and has 1 first. ms is counted as a positive integer of 6 digits (although there is a possibility of 7 digits). Register with the last number of nt (the last digit) and prime factorize. In the upper number, the last digit of nt is 7. The last digit of nt is 7 (3, 19) (7, 11) (13, 19) (13, 29) (19, 23) (23, 29) . A program that prime factorization can be solved quickly when paying attention to the last 7. First, divide by 3, 7, 11, 13, 17, 19, 23, 29 to see if it is an integer. If it is an integer it has that number as a prime factor. The last 607 of 1976869607 is a prime number. A huge odd number (one multiplied by a huge prime number and a huge prime number) can be factorized using this factor. By using this, it seems that the rupture of the RSA encryption becomes faster.

The Domain of the Riemann Zeta Function on the Complex Plane

Authors: Armando M. Evangelista Jr.
Comments: 4 Pages.

The Riemann zeta-function is one of the most studied complex function in mathematics. Riemann in his 1859 paper On the Number of Prime Numbers less than a Given Quantity [1] claimed that the analytic continuation of the zeta-function extends its domain over the entire complex plane except at s = 1. But, as I’ve shown in my two papers: A Short Disproof of the Riemann Hypothesis [2] and Riemann’s Functional Equation is Not a Valid Function and Its Implication on the Riemann Hypothesis [3], the zeta-function is only defined on the right half-plane. It is the purpose of this present work to precisely locate the domain of this function on the right half-plane.

Riemann’s Functional Equation is Not a Valid Function and Its Implication on the Riemann Hypothesis

Authors: Armando M. Evangelista Jr.
Comments: 10 Pages.

Riemann’s functional equation was formulated by Riemann himself in order to extend the domain of the zeta function from the right half-plane into the entire complex plane except at s = 1. It also lead him to find a real function, so that, at s = ½ + ωi, the real function has zeros for some values of ω. Now, the real function was also related to the zeta function, which in turn has something to do with the distribution of prime numbers. This drove him to developed a formula of relating the zeros of the zeta function to the number of primes given a certain number. Riemann then conjectured that all the zeros of the zeta function are at s = ½ + ωi, which is now known as the Riemann Hypothesis. Hence, Riemann’s functional equation is the foundation upon which the Riemann Hypothesis is based. But, there is one problem, the function as shall be shown here, suffers from not being able to yield meaningful or valid values, as it should. Also, if one carefully examine on how Riemann arrived at his formula, I for one, found it to be unsatisfactory or unconvincing. It is, therefore, the aim of this present work to show, that, if carefully examined, Riemann’s functional equation could not be a valid function, and consequently, the Riemann Hypothesis crumbles on its claim.

A Short Disproof of the Riemann Hypothesis

Authors: Armando M. Evangelista Jr.
Comments: 3 Pages.

The Riemann Hypothesis is one of the most important unsolved problem in Mathematics: its validity will have have a great consequence on the precise calculation of the number of primes. Riemann developed an explicit formula relating the number of primes with the hypothesized non-trivial zeros of the Riemann zeta function. Riemann hypothesis states that all the non-trivial zeros of the zeta function have real part equal to one-half on the critical strip. Despite many attempts to solve it for about 150 years, no one have, so far succeeded. Riemann hypothesis is based on the existence of the zeros of the zeta function. If it can be shown, that, such zeros do not exist, then, the Riemann Hypothesis is false.

Investigated Prime Numbers Corresponding to Nontrivial Zeros of Riemann Hypothesis

Authors: Toshiro Takami
Comments: 20 Pages.

We investigated prime numbers corresponding to nontrivial zeros. We used walframalpha which exists on the net for all calculation and drawing. In the complex plane, the non-trivial zeros of the zeta function were thought that there were non-trivial zeros besides x = 0.5, and I examined them variously, but they did not show the tendency to converge at all and were inferred to be absent. The zeros of the zeta function probably existed indefinitely at x = 0.5, but they were inferred to be absent elsewhere. In the walframalpha 's Parametric plot, I understood the convergence well. The first zero point at x = 0.5 was set as T1 = 14.1347, and the corresponding prime number was obtained. In the following, prime numbers corresponding to nontrivial zero points T2 = 21.022, T3 = 25.0108, etc. were obtained.

A Generalized Solution to a Specific Type of Power Series and its Trigonometric and Hyperbolic Extensions

Authors: Abdalla M. Aboarab
Comments: 12 Pages.

In this paper, the power series is looked at from a different perspective. The Summation of $n^{m}a^{-bn}$ is evaluated using a new method. An assumption is made that the power $-bn$ is multiplied by $x$ where $ x=1$; then the series is integrated m times in order to cancel the term $n^{m} $ out leaving the term $a^{-bn}$. By simply taking the derivative of the result m-times, an expression to evaluate the series arises, which include only a constant term and the m$^{th}$ order derivative of the summation of a simple geometric series. Further applications of the method are used to evaluate the series with the cosine, sine, hyperbolic sine, and hyperbolic cosine. Finally, the method is used to further simplify some of the hardest forms of series to deal with: the series $n^{m}$sinh$^{v}(ny)$, and $n^{m}$cosh$^{v}(ny)$ and $n^{m}$sin$^{v}(ny)$.

New Multiple Attribute Decision Making Method Based on DEMATEL and TOPSIS for Multi-Valued Interval Neutrosophic Sets

Authors: Wei Yang, Yongfeng Pang
Comments: 16 Pages.

Interval neutrosophic fuzzy decision making is an important part of decision making under uncertainty, which is based on preference order. In this study, a new multi-valued interval neutrosophic fuzzy multiple attribute decision making method has been developed by integrating the DEMATEL (decision making trial and evaluation laboratory) method and the TOPSIS (the technique for order preference by similarity to an ideal solution) method. Evaluation values are given in the form of multi-valued interval neutrosophic fuzzy values. By using DEMATEL, dependencies among attributes can be modeled, and attribute weights are determined.

New Similarity Measures of Simplified Neutrosophic Sets and Their Applications

Authors: Chunfang Liu
Comments: 11 Pages.

The simplified neutrosophic set (SNS) is a generalization of fuzzy set that is designed for some practical situations in which each element has truth membership function, indeterminacy membership function and falsity membership function. In this paper, we propose a new method to construct similarity measures of single valued neutrosophic sets (SVNSs) and interval valued neutrosophic sets (IVNSs), respectively. Then we prove that the proposed formulas satisfy the axiomatic definition of the similarity measure. At last, we apply them to pattern recognition under the single valued neutrosophic environment and multi-criteria decision making problems under the interval valued neutrosophic environment. The results show that our methods are effective and reasonable.

On Neutrosophic Paraconsistent Topology

Authors: Francisco Gallego Lupiáñez
Comments: 6 Pages.

Recently, F. Smarandache generalized the Atanassov’s intuitionistic fuzzy sets and other kinds of sets to neutrosophic sets (NSs). Also, this author introduced a general definition of neutrosophic topology. On the other hand, there exist various kinds of paraconsistent logics, where some contradiction is admissible. The purpose of this paper is to show that a Smarandache’s definition of neutrosophic paraconsistent topology is not a generalization of C¸ oker’s intuitionistic fuzzy topology (IFT) or Smarandache’s general neutrosophic topology.

Authors: Y.Rameswara Reddy, B.Chandra Mohana Reddy
Comments: 7 Pages.

This paper presents a study that investigates the effect of the WEDM process parameters on the surface roughness, MRR and DD of the Super Ni 718 supper alloy. Twenty seven experimental runs based on an orthogonal array of Taguchi method are performed and grey relational analysis with SVNS for weightages is applied to determine an optimal WEDM parameter setting. Surface roughness, MRR and DD are selected as the quality targets. An optimal parameter combination of the WEDM process is obtained using Grey relational analysis with SVNS. By analyzing the Grey relational grade matrix, the degree of influence for each controllable process factor onto individual quality targets can be found and the ranks are obtained.

Decision-Making Approach Based on Neutrosophic Rough Information

Authors: Muhammad Akram, Nabeela Ishfaq, Sidra Sayed, Florentin Smarandache
Comments: 20 Pages.

Rough set theory and neutrosophic set theory are mathematical models to deal with incomplete and vague information. These two theories can be combined into a framework for modeling and processing incomplete information in information systems. Thus, the neutrosophic rough set hybrid model gives more precision, flexibility and compatibility to the system as compared to the classic and fuzzy models. In this research study, we develop neutrosophic rough digraphs based on the neutrosophic rough hybrid model. Moreover, we discuss regular neutrosophic rough digraphs, and we solve decision-making problems by using our proposed hybrid model. Finally, we give a comparison analysis of two hybrid models, namely, neutrosophic rough digraphs and rough neutrosophic digraphs.

Neutrosophic Soft Set Decision Making for Stock Trending Analysis

Authors: Sudan Jha, Raghvendra Kumar, Le Hoang Son, Jyotir Moy Chatterjee, Manju Khari, Navneet Yadav, Florentin Smarandache
Comments: 7 Pages.

In this paper, we point out a major issue of stock market regarding trending scenario of trades where data exactness, accuracy of expressing data and uncertainty of values (closing point of the day) are lacked. We use neutrosophic soft sets (NSS) consisting of three factors (True, Uncertainty and False) to deal with exact state of data in several directions. A new approach based on NSS is proposed for stock value prediction based on real data from last 7 years. It calculates the stock price based on the factors like “open”, “high”, “low” and “adjacent close”. The highest score value retrieved from the score function is used to determine which opening price and high price decide the closing price from the above mentioned four factors.

Spanning Tree Problem with Neutrosophic Edge Weights

Authors: Said Broumi, Assia Bakali, Mohamed Talea, Florentin Smarandache, Arindam Dey, Le Hoang Son
Comments: 10 Pages.

Neutrosophic set and neutrosophic logic theory are renowned theories to deal with complex, not clearly explained and uncertain real life problems, in which classical fuzzy sets/models may fail to model properly. This paper introduces an algorithm for finding minimum spanning tree (MST) of an undirected neutrosophic weighted connected graph (abbr. UNWCG) where the arc/edge lengths are represented by a single valued neutrosophic numbers. To build the MST of UNWCG, a new algorithm based on matrix approach has been introduced. The proposed algorithm is compared to other existing methods and finally a numerical example is provided.

Study on the Development of Neutrosophic Triplet Ring and Neutrosophic Triplet Field

Authors: Mumtaz Ali, Florentin Smarandache, Mohsin Khan
Comments: 10 Pages.

Rings and fields are significant algebraic structures in algebra and both of them are based on the group structure. In this paper, we attempt to extend the notion of a neutrosophic triplet group to a neutrosophic triplet ring and a neutrosophic triplet field. We introduce a neutrosophic triplet ring and study some of its basic properties. Further, we define the zero divisor, neutrosophic triplet subring, neutrosophic triplet ideal, nilpotent integral neutrosophic triplet domain, and neutrosophic triplet ring homomorphism. Finally, we introduce a neutrosophic triplet field.

Authors: Mai Mohamed, Mohamed Abdel-Basset, Abdel-Nasser Hussien, Florentin Smarandache
Comments: 11 Pages.

Neutrosophic sets have been introduced as a generalization of crisp sets, fuzzy sets, and intuitionistic fuzzy sets to represent uncertain, inconsistent and incomplete information about real world problems. Elements of neutrosophic set are characterized by a truthmembership, falsity-membership and indeterminacy membership functions.

In this paper, we tried to draw a fair assessment on things which will take place soon with the coming era of IoT, 5G technology, global eavesdropping and all that. Nonetheless, we are aware that this article sounds quite gloomy. We are not techno-utopians (read Evvgeny Morozov’s WSJ article on digital dictatorship1), but we are not techno-pessimists either. Perhaps you can consider us as: "techno-realists."2 This paper was written in the same spirit of Jonathan L. Zittrain’s book The Future of Internet and how to stop it.

Understanding the "Chain Rule" by Deriving Your Own Version

Authors: James A. Smith
Comments: 12 Pages.

Because the Chain Rule can confuse students as much as it helps them solve real problems, we put ourselves in the shoes of the mathematicians who derived it, so that students may understand the motivation for the rule; its limitations; and why textbooks present it in its customary form. We begin by finding the derivative of sin2x without using the Chain Rule. That exercise, having shown that even a comparatively simple compound function can be bothersome to differentiate using the definition of the derivative as a limit, provides the motivation for developing our own formula for the derivative of the general compound function g[f(x)]. In the course of that development, we see why the function f must be continuous at any value of x to which the formula is applied. We finish by comparing our formula to that which is commonly given.

Shellability is NP-complete

Authors: Thinh Nguyen
Comments: 19 Pages.

We prove that for every d≥2, deciding if a pure, d-dimensional, simplicial complex is shellable is NP-hard, hence NP-complete. This resolves a question raised, e.g., by Danaraj and Klee in 1978. Our reduction also yields that for every d≥2 and k≥0, deciding if a pure, d-dimensional, simplicial complex is k-decomposable is NP-hard. For d≥ 3, both problems remain NP-hard when restricted to contractible pure d-dimensional complexes. Another simple corollary of our result is that it is NP-hard to decide whether a given poset is CL- shellable.

Erd ̋os-Szekeres is NP-Hard in 3 Dimensions and What Now?

Authors: Thinh Nguyen
Comments: 4 Pages.

The Erd ̋os-Szekeres theorem states that, for every $k$, there is a number $n_k$ such that every set of $n_k$ points in general position in the plane contains a subset of $k$ points in convex position. If we ask the same question for subsets whose convex hull does not contain any other point from the set, this is not true: as shown by Horton, there are sets of arbitrary size that do not contain an empty 7-gon. These questions have also been studied extensively from a computational point of view, and polynomial time algorithms for finding the largest (empty) convex set have been given for the planar case. In higher dimension, it is not known how to compute such a set efficiently. In this paper, we show that already in 3 dimensions no polynomial time algorithm exists for determining the largest (empty) convex set (unless $P$=$NP$), by proving that the corresponding decision problem is $NP$-hard. This answers a question by Dobkin, Edelsbrunner and Overmars from 1990. As a corollary, we derive a similar result for the closely related problem of testing weak $ε$-nets in $R^3$ . Answering a question by Chazelle et al. from 1995, our reduction shows that the problem is $co-NP$-hard. Finally, we make several suggestions for further research on the subject.

The Majority Rule and Combinatorial Geometry (Via the Symmetric Group)

Authors: Thinh Nguyen
Comments: 0 Pages.

The Marquis du Condorcet recognized 200 years ago that majority rule can produce intransitive group preferences if the domain of possible (transitive) individual preference orders is unrestricted. We present results on the cardinality and structure of those maximal sets of permutations for which majority rule produces transitive results (consistent sets). Consistent sets that contain a maximal chain in the Weak Bruhat Order inherit from it an upper semimodular sublattice structure. They are intrinsically related to a special class of hamiltonian graphs called persistent graphs. These graphs in turn have a clean geometric interpretation: they are precisely visibility graphs of staircase polygons. We highlight the main tools used to prove these connections and indicate possible social choice and computational research directions.

Simulation of Nontrivial Zero of Riemann Zeta Function  Ver.2

Authors: Toshiro Takami
Comments: 3 Pages.

Simulation of the nontrivial zero of Riemann's prediction succeeded in mimicking with rotational force alone. Although it is a simulation with only the rotational force, it is a very approximate value because the initial value was set as the first nonzero point of the Riemann zeta function. We adopted a method of placing a rotating force on the previous value and stacking it. I could reproduce how the dragon climbs up the x = 0.5 axis. The expressions a1, a2, a3, a4, a5, a6 ... are 1, 2, 3, 4, 5, 6 ....... In 1.0 of the interval of the nuclear energy, simulation did not hold and it was forced to take the value of 1.1. At first, although it is out of the nonobvious point of Riemann's prediction, it gradually becomes an approximate value. However, this may also be lower than the previous value, and it should be improved in the future.

Simulation of Nontrivial Zero of Riemann Zeta Function ver.1

Authors: Toshiro Takami
Comments: 9 Pages.

We simulated the nontrivial zeros of Riemann's prediction. Looking at every other degree of increase, there is a maximum point of increase in every fourth, third or fifth place. For that reason, we did not only change one another but we looked at differences from two, three, four, five, six, seven and so on, but the degree of increase has changed variously Was observed. This is reminiscent of the dragon which rises x = 0.5 while changing the degree of freedom freely while drawing a circle. Initially we tried to simulate a nontrivial point with only the degree of increase of the circle, but we thought that it was impossible without increasing regularity and we adopted ln(x!). And averaged the increase. The average increase is 2πln(x!) = N (n is an integer starting from 1). The expression of this increase degree is expressed as follows. when ln(x!) = 1 Increase +2.31244 when ln(x!) = 2 Increase +3.16283 when ln(x!) = 3 Increase +3.88072 And so on.

The Domain of the Riemann Zeta Function on the Complex Plane

Authors: Armando M. Evangelista Jr.
Comments: I’ve made a mistake on the starting value for k in the double sum on pages 2 and 3, it should start at k =1.

The Riemann zeta-function is one of the most studied complex function in mathematics. Riemann in his 1859 paper On the Number of Prime Numbers less than a Given Quantity [1] claimed that the analytic continuation of the zeta-function extends its domain over the entire complex plane except at s = 1. But, as I’ve shown in my two papers: A Short Disproof of the Riemann Hypothesis [2] and Riemann’s Functional Equation is Not a Valid Function and Its Implication on the Riemann Hypothesis [3], the zeta-function is only defined on the right half-plane. It is the purpose of this present work to precisely locate the domain of this function on the right half-plane.
