Modelling a problem in quantum chemistry, within the framework of Hartree-Fock approach, requires the evaluation of four-center two-electron integrals. The speed up of the integral evaluation is a key point in order to get a method suitable to deal w

A new approach for evaluating the four-center bielectronic integrals (12|34), involving 1s Slater-type orbitals, is presented. The method uses the multiplication theorem for Bessel functions. The bielectronic integral is expressed in terms of a finit

This article presents a variation of the integral transform method to evaluate multicenter bielectronic integrals (12|34), with 1s Slater-type orbitals. It is proved that it is possible to define, out of the expression of (12|34) given by the integra

In this paper we consider the problem of finding periodic solutions of certain Euler-Lagrange equations. We employ the direct method of the calculus of variations, i.e. we obtain solutions minimizing certain functional I. We give conditions which ens

In this paper, we analyze an optimization problem for the first (nonlinear) Steklov eigenvalue plus a boundary potential with respect to the potential function which is assumed to be uniformly bounded and with fixed $L^1$-norm.
