## Abstract A new method has been proposed for calculating the Gaussian matrix elements of the interaction operator represented by an arbitrary degree of interelectron distance __X__. The method is based on the expansion of two‐electron integrals as the sum of one‐electron integrals which in turn a

A system of functions 0-normalized with respect to the operator βˆ† in some domain Ω βŠ‚ R n is constructed. Application of this system to boundary value problems for the polyharmonic equation is considered. Connection between harmonic functions and solutions of the Helmholtz equation is investigated.
