Policies for Constraining the Behaviour of Coalitions of Agents in the Context of Algebraic Information Theory

Authors: Christopher Goddard
Comments: 27 Pages.

This article takes an oblique sidestep from two previous papers, wherein an approach to reformulation of game theory in terms of information theory, topology, as well as a few other notions was indicated. In this document a description is provided as to how one might determine an approach for an agent to choose a policy concerning which actions to take in a game that constrains behaviour of subsidiary agents. It is then demonstrated how these results in algebraic information theory, together with previous investigations in geometric and topological information theory, can be unified into a single cohesive framework.

Press Release: Multiplication of Triplets

Authors: Clumsy Foo
Comments: 8 Pages. Every mathematical proof is only valid for the range of the few axioms, on which its construction is based! English and German press release.

To all appearances mathematicians are not interested in mathematics, but they are only interested in constructing proofs. After having found a proof that a mathematical statement is correct or wrong, or that a mathematical construction is possible or impossible, mathematicians stop thinking about these statements or constructions. This is problematic for a science which is axiomatically founded in such a severe way.

Hypercomplex Numbers of Dimension 11

Authors: Valery Timin
Comments: timinva@yandex.ru, 3 pages in Russian

This work is devoted to the search, study and compilation of the multiplication table of a compound hyperbolic (Hypercomplex) number of dimension nine (11): q = {1, i1, i2, i3, …, i10, }: in2 = 1. On this basis, as a template, you can choose other multiplication tables with a different target or arbitrary arrangement of plus (+) and minus (-) characters in the cells of the multiplication table. The disadvantage of multiplication tables of dimension 11 is that they are neither associative nor commutative (not even anticommutative). But this is their fundamental property.. Эта работа посвящена поиску, изучению и составлению таблицы умножения составного гиперболического (гиперкомплексного) числа размерностью девять (11): q = {1, i1, i2, i3, …, i11, }: in2 = 1. На этой основе как на шаблоне можно подобрать другие таблицы умножения с другой целевой или произвольной расстановкой знаков "плюс" (+) и "минус" (-) в ячейках таблицы умножения. Ассоциативных и коммутативных таблиц умножения не имеется.

The Two Couriers Problem

Authors: William F. Gilreath
Comments: 6 Pages. Published in Transmathematica 2019

The Two Couriers Problem is an algebra problem, originally stated in 1746 by the French mathematician Clairaut. For over a century, the Two Couriers Problem has been re-used in various forms as a mathemat- ical problem, in textbooks and journals, by different mathematicians and authors. The Two Couriers Problem involves cases where division by zero arises in practice, where each has a real-world, actual result for the solution. Thus the Two Couriers Problem is a centuries old algebra problem with actual applied results that involve division by zero. It is an excellent mathematical problem to evaluate different methods for dividing by zero. Division by zero has many different mathematical approaches. Conventional mathematics handles division by zero as an indeterminate or undefined result. Transmathematics defines division by zero as either nul- lity or explicitly positive or negative infinity. Two other approaches are by Saitoh, who defines division by zero simply as zero, and Barukčić who defines division by zero as either unity or explicitly positive or implicitly negativity infinity. The question is, which approach is best to solve the mathematical problem of division by zero? The paramount goal of this paper is to use the Two Couriers Problem as an objective test to examine and evaluate mathematical approaches to division by zero – and find which one is best.

Unimodular Rotation of E8 to H4 600-Cells

Authors: J Gregory Moxness
Comments: 5 Pages.

We introduce a unimodular Determinant=1 8x8 rotation matrix to produce four 4 dimensional copies of H4 600-cells from the 240 vertices of the Split Real Even E8 Lie group. Unimodularity in the rotation matrix provides for the preservation of the 8 dimensional volume after rotation, which is useful in the application of the matrix in various fields, from theoretical particle physics to 3D visualization algorithm optimization.

Some Facts on Permanents in Finite Characteristics

Authors: Anna Knezevic, Greg Cohen
Comments: 75 Pages. This research was partly supported by the School of Electrical Engineering, Computing and Mathematical Sciences of the Curtin University (Australia)

The permanent’s polynomial-time computability over fields of characteristic 3 for k-semi-unitary matrices (i.e. n×n-matrices A such that rank(AA^T-I_n )=k) in the case k ≤ 1 and its #_3P-completeness for any k > 1 (Ref. 9) is a result that essentially widens our understanding of the computational complexity boundaries for the permanent modulo 3. Now we extend this result to study more closely the case k > 1 regarding the (n-k)×(n-k)-sub-permanents (or permanent-minors) of a unitary n×n-matrix and their possible relations, because an (n-k)×(n-k)-submatrix of a unitary n×n-matrix is generically a k-semi-unitary (n-k)×(n-k)-matrix. The following paper offers a way to receive a variety of such equations of different sorts, in the meantime also extending (in its second chapter divided into subchapters) this direction of research to reviewing all the set of polynomial-time permanent-preserving reductions and equations for a generic matrix’s sub-permanents they might yield, including a number of generalizations and formulae (valid in an arbitrary prime characteristic) analogical to the classical identities relating the minors of a matrix and its inverse. Moreover, the second chapter also deals with the Hamiltonian cycle polynomial in characteristic 2 that surprisingly demonstrates quite a number of properties very similar to the corresponding ones of the permanent in characteristic 3. Besides, the paper’s third chapter is devoted to the computational complexity issues of the permanent and some related functions on a variety of Cauchy matrices and their certain generalizations, including constructing a polynomial-time algorithm (based on them) for the permanent of an arbitrary square matrix in characteristic 5 and conjecturing the existence of a similar scheme in characteristic 3. Throughout the paper, we investigate various matrix compressions and transformations preserving the permanent and related functions in certain finite characteristics. And, as an auxiliary algebraic tool supposed for an application when needed in all the constructions we’re going to discuss in the present article, we’ll introduce and utilize a special principle involving a field’s extension by a formal infinitesimal and allowing, provided a number of conditions are fulfilled, to reduce the computation of a polynomial over a field to solving a system of algebraic equations in polynomial time. greg.cohen.math@gmail.com

Sketches On Polysigns And Other Arithmetics Operators

Authors: Kujonai
Comments: 48 Pages.

A compilation of drawings sprung during a email exchanging with T. Golden, author of the Polysigns numbers. It must be mentioned that he accepts only some of the concepts presented here. Although we do share some common ground while talking about Polysigns and/or "simplexogonal" arithmetics, we do have some differences in the approach. In anycase, it is required some understanding of the Polysign Notation to fully appreciate the drawings. A few important bits arose as a direct consequence of the interaction and some are presented here, in a rather highly informal way.

Form Invariant High Order Differentials

Authors: Han Xiao
Comments: 19 Pages.

Traditionally, an infinitesimal is regarded as a variable that runs toward 0. Since a differential is a kind of infinitesimal, a differential is essentially a variable running toward 0 too. As a result, differentials are form invariant but not meaning invariant. This paper proposes a Number Field of Ordered Infinitesimals and Infinities (OII Number Field) which can be seen as a kind of extension of real number field. The terminus of a variable running toward 0 is no longer 0, but a point in the OII Number Field, with an Order and a Weight. In this way, the process of running is recorded in the destination, making infinitesimals a kind of number which can be compared and operated easily. On this basis, the differential of a variable is invariant not only in form, but also in meaning. As a differential becomes a variable on another number axis parallel to the real number axis in OII Number Field, a differential can generate differential too, thus giving rise to high order differentials which are also invariant both in form and in meaning.

Through my most extensive research, I have made a groundbreaking discovery. While many of us are familiar with binomial theorem and the polynomial multiplication algorithm, "First Outside Inside Last", there are also a set of rules that apply in field R. For instance, (a+b)^2 expands to a^2+b^2, and (a+b)(a-b) expands to a+b. This paper seeks to prove these rules in a simple and geometric manner.

To each monoid M we attach an inclusion A --> B of Q-algebras, and ask: Is B flat over A? If our monoid M is a group, A is von Neumann regular, and the answer is trivially Yes in this case.

Direct Sum Decomposition of a Linear Vector Space

Authors: Anamitra Palit
Comments: 5 Pages.

The direct sum decomposition of a vector space has been explored to bring out a conflicting feature in the theory. We decompose a vector space using two subspaces. Keeping one subspace fixed we endeavor to replace the other by one which is not equal to the replaced subspace. Proceeding from such an effort we bring out the conflict. From certain considerations it is not possible to work out the replacement with an unequal subspace. From alternative considerations an unequal replacement is possible.

Comments: 3 Pages.

Let G be a finite nontrivial group, let X be a finite faithful G-set, let P^i(X) be the i-th power set of X, let n(i) be the number of points of P^i(X), let m(i) be the number of points of P^i(X) with non-trivial stabilizer, let k be the number of prime order subgroups of G, and set E(j):=2^j for any integer j. We prove that n(i)/m(i) is at least E(n(i-1)/4)/k for i>1.

Construction of Multivector Inverse for Clif Ford Algebras Over 2m+1-Dimensional Vector Spaces from Multivector Inverse for Clifford Algebras Over 2m-Dimensional Vector Spaces

Authors: Eckhard Hitzer, Stephen J. Sangwine
Comments: Advances of Applied Clifford Algebras, Vol. 29, article #29, 22 pages, First Online: 19 February 2019. DOI: 10.1007/s00006-019-0942-7.

Assuming known algebraic expressions for multivector inverses in any Clifford algebra over an even dimensional vector space R^{p',q'), n' = p' +q' = 2m, we derive a closed algebraic expression for the multivector inverse over vector spaces one dimension higher, namely over R^{p,q}, n = p+q = p'+q'+1 = 2m+1. Explicit examples are provided for dimensions n' = 2,4,6, and the resulting inverses for n = n' +1 = 3,5,7. The general result for n = 7 appears to be the first ever reported closed algebraic expression for a multivector inverse in Clifford algebras Cl(p,q), n = p + q = 7, only involving a single addition of multivector products in forming the determinant.

Review on Rationality Problems of Algebraic K-Tori

Authors: Youngjin Bae
Comments: 12 Pages.

Rationality problems of algebraic $k-tori$ is closely related to rationality problems of the invariant field, also known as Noether's Problem. We describe how a function field of algebraic $k-tori$ can be identified as an invariant field under a group action and that a $k-tori$ is rational if and only if its function field is rational over $k$. We also introduce character group of $k-tori$ and numerical approach to determine rationality of $k-tori$.

Splitting of Quasi-Definite Linear System Maintains Inertia

Authors: Martin Neuenhofen
Comments: 4 Pages.

We show that there is a variety of Schur complements that yield a decoupling of a quasi-definite linear system into two quasi-definite linear systems of half the size each. Splitting of linear systems of equations via Schur complements is widely used to reduce the size of a linear system of equations. Quasi-definite linear systems arise in a variety of computational engineering applications.

On The Non-Real Nature of x.0 (x \in R_{\ne 0}): The Set of Null Imaginary Numbers $\nullset$

Authors: Saulo Queiroz
Comments: 6 Pages.

In this letter we discuss the inconsistencies of $0/0\cdot x=y$, $x,y\in\real_{\ne 0}$ from the perspective of the zero property multiplication (ZPM) $x\cdot 0 = y\cdot 0$ on $\real$. We axiomatize $x\cdot 0$ as a number $\inull(x)$ that has a real part $\Re(\inull(x))=0$ but indeed is not real. From this we define the set of null imaginary numbers $\nullset$ as $\{\inull(x)|\forall x\in\real_{\ne 0}\} \cup \{0\}$. Based on the definition of uniqueness (i.e., if $x\ne y\Leftrightarrow \inull(x)\ne \inull(y)$ and the null division (i.e., $\inull(x)/0=x$) we show the elementar algebra of $\nullset$. Hence, under the condition of existence of $\nullset$, we show that $0/0=1$ does cause the logic trivialism of mathematic.

The main purpose of this paper is to study and investigate certain results concerning the (σ,τ)-generalized derivation D associated with the (σ,τ)-derivation d of semiprime and prime rings R, where σ and τ act as two automorphism mappings of R. We focus on the composition of (σ,τ)-generalized derivations of the Leibniz’s formula, where we introduce the general formula to compute the composition of the (σ,τ)-generalized derivation D of R.

On The Non-Real Nature of x.0 (x in R*): The Set of Null Imaginary Numbers

Authors: Saulo Jorge
Comments: 7 Pages.

In this work I axiomatize the result of $x \cdot 0$ ($x\in\real_{\ne 0}$) as a number $\inull(x)$ that has a null real part (denoted as $\Re(\inull(x))=0$) but that is not real. This implies that $y+\Re(\inull(x)) = y$ but $y+\inull(x) = y + x\cdot 0 \not=y$, $y\in\real_{\ne 0}$. From this I define the set of null imaginary numbers $\nullset=\{\inull(x)=x\cdot 0|\forall x\in\real_{\ne 0}\}$ and present its elementary algebra taking the axiom of uniqueness as base (i.e., if $x\ne y\Leftrightarrow \inull(x)\ne \inull(y)$). Under the condition of existence of $\nullset$ I show that division by zero can be defined without causing inconsistencies in elementary algebra.
