Completely regular semigroups

1995
Abstract It is well known that a group (G, μ) can alternatively be regarded as having three operations, namely the binary operation μ : (a, b)  ⟼ab, the unary operation a ⟼a-1, and the 0-ary operation (the constant) 1.

Semigroup Rings of Completely Regular Semigroups

1990
A semigroup S is said to be completely regular if and only if it is covered by its subgroups; that is, if and only if, for each a ∈ S, a ∈ a2 S∩S a2. Groups and bands (semigroups of idempotents) are extreme special cases. In this paper a survey is given of results on the Jacobson radical of the semigroup ring of a completely regular semigroup over a ...
