Decompositions of the congruence lattice of a semigroup
Walter Douglas Munn · Proceedings of the Edinburgh Mathematical Society · 1980
The purpose of this note is to extend the results of Reilly and Scheiblich (6) (see also Scheiblich (7) and Hall (2)) on the θ-class decomposition of the congruence lattice of a regular semigroup and, at the same time, to provide an alternative proof of these results.
