Congruences on an inverse Bruck-Reilly monoid. Part I: Non-group congruences.
Congruences on bands of π-groups
A semigroup S is said to be completely π-regular if for any a ∈ S there exists a positive integer n such that aⁿ is completely regular. The present paper is devoted to the study of completely regular semigroup congruences on bands of π-groups.
