Abstract

Traditional methods of research for the Galois group of a polynomial fwith coefficients in a field Kare strongly related to factorization of absolute or relative resolvents. In this paper, thanks to resolvents and the Galois theory for rings, we describe an effective algorithm for building a splitting field Eof fover K, i.e. to find a finite system of generators for the kernel of a surjective morphism .
