Abstract

An algorithm of polynomial complexity is described for factoring polynomials in several variables into irreducible factors over a field F which is finitely generated over the prime subfield H. An algorithm is also constructed for finding the components of the protective variety of common roots of homogeneous polynomials

(let c−1 denote its dimension) with working time polynomial in

. where

, the number L is the size of the representation of the polynomials

and
