ON THE CAYLEY SEMIGROUP OF A FINITE APERIODIC SEMIGROUP
Avi I. Mintz · International Journal of Algebra and Computation · 2009
Let S be a finite semigroup. In this paper, we introduce the functions φs:S* → S*, first defined by Rhodes, given by φs([a1,a2,…,an]) = [sa1,sa1a2,…,sa1a2 ⋯ an]. We show that if S is a finite aperiodic semigroup, then the semigroup generated by the functions {φs}s ∈ S is finite and aperiodic.
