Abstract:

Let A be a ring with identity. The generalized affine transformation monoid Gaff ( A ) is defined as the set of all transformations on A of the form x ↦ x u + a (for all x ∈ A ), where u , a ∈ A . We study the algebraic structure of the monoid Gaff ( A ) on a finite Galois ring A . The following results are obtained: an explicit description of Green's relations on Gaff ( A ) ; and an explicit description of the Schützenberger group of every -class, which is shown to be isomorphic to the affine transformation group for a smaller Galois ring.
