The Fixed Subring of Some Groups of Ring Automorphisms
Published online by Cambridge University Press: 20 November 2018
Abstract
Let Zm denote the ring of integers modulo an integer m > 1 and let G(Zm) be the group under composition of all Zm-automorphisms of Zm[X]. In this paper we determine Zm[X]G(zm) the subring of Zm[X] left fixed by elements of G(Zm).
