Special Congruence Triples for a Regular Semigroup

With the usual notation for congruences on a regular semigroup S, in a previous communication we studied the lattice Λ generated by Γ = {σ, τ, μ, β} relative to properties such as distributivity and similar conditions. For K and T the kernel and trace relations on the congruence lattice of S, we form an abstraction of the triple (Λ;K|Λ, TΛ) called a c-triple. In this study a number of relations...

new semigroup compactifications via the enveloping semigroups of associated flows

this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.

On the Cayley Semigroup of a Finite Aperiodic Semigroup

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.
