In his 1859 paper, Bernhard Riemann used an integral equation to develop an explicit formula for estimating the number of prime numbers less than a given quantity. It is the purpose of this present work to explore some of the properties of this integral equation.

In the present paper, new multifractal analysis of vector valued Ahlfors type measures is developed. Mutual multifractal generalizations f fractal measures such as Hausdorff and packing have been introduced with associated dimensions. Essential properties of these measures have been shown using convexity arguments.

Tetrahedral discretizations of the multielectron Schrödinger operator are suggested. They is based on tetrahedral triangulations of domains in R^{3}. Theoretical results proving that these discretizations are able to approximate energy levels of electrons in atoms and molecules are obtained.

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.

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.
