Abstract
The relationship between the topological structure of the multidimensi onal configuration space and the structure of the symmetrical permutat ion group SN is analyzed. This relationship permits to separate the sp in and spatial variables during the solution of the spinless stationar y Schrodinger equation. It is possible to simplify the construction of wave functions for N-electron systems and to expand the class of tria l functions in the variation method. The relation of the suggested app roach to the construction of wave functions by traditional methods is demonstrated by the example of three-electron systems.
