Abstract

A general method of evaluation of traces of arbitrary powers of Hermitian operators containing one- and two-body interactions and defined in a finite-dimensional model space is presented. The model space is taken as the antisymmetric and spin-adapted part of an N-fold Cartesian product of a one-electron space. The method is based on the symmetric group approach to the theory of many-electron systems.
