More Sine Function at Rational Argument, Product of Gamma Functions and Infinite Product Representations

Authors: Edigles Guedes
Comments: 9 Pages.

I derived an identity involving gamma functions and sine function at rational argument; hence, the representation of infinite product arose.

Tetrahedral Discretizations of the Schrödinger Operator for the Purposes of Quantum Chemistry

Authors: Ruslan Sharipov
Comments: Designed for double sided printing, US Letter size, 35 pages, 5 color figures

Tetrahedral discretizations of the multielectron Schrödinger operator are suggested. They is based on tetrahedral triangulations of domains in R3. Theoretical results proving that these discretizations are able to approximate energy levels of electrons in atoms and molecules are obtained.

On the Properties of the Two-Sided Laplace Transform and the Riemann Hypothesis

Authors: Seong Won Cha
Comments: 22 Pages.

We will show interesting properties of two-sided Laplace transform, mainly of positive even functions. Further, we will also prove that the Laguerre inequalities and generalized Laguerre inequalities are true and finally, the Riemann hypothesis is true.

Cosine Function at Rational Argument and Infinite Product Representation

Authors: Edigles Guedes
Comments: 4 Pages.

I used an identity for cosine function involving finite sum of the gamma functions; hence, the representation of infinite product arose.

Sine Function at Rational Argument, Finite Product of Gamma Functions and Infinite Product Representation

Authors: Edigles Guedes
Comments: 6 Pages.

I corrected the Theorem 21 of previous paper, obtaining an identity for sine function at rational argument involving finite sum of the gamma functions; hence, the representation of infinite product arose.
