## Abstract

Abstract The problem of expanding a rational function of several variables into terms with separable variables is formulated. An algorithm for solving this problem is given. Programs which implement this algorithm can occur in sets of algebraic alphabetical transformations on a computer and can be used to reduce the multiplicity of sums and integrals of rational functions for investigating differential equations with rational right-hand sides etc.
