Completely Regular Semigroups
Petrich, Mario / Reilly, Norman R
Present a systematic treatment of completely regular semigroups, from introductory to research level, comprised of preliminaries on lattices, semigroups, varieties, and complete regularity, congruences and relations on the congruence lattice, and varieties of completely regular semigroups through kernals, and traces of congruences and Malcev products.
