This book is a unified treatment of the most important core developments in the theory of completely regular semigroup theory as it stands today. This volume focuses on the lattice of varieties of completely regular semigroups. Since any in-depth study of the lattice of varieties requires an understanding of free completely regular semigroups, the book begins by describing the free object on countably infinite sets and the properties of the lattice of fully invariant congruences on the free object. The authors then introduce the various relations and operators on the lattice of varieties of completely regular semigroups. The book then covers the sublattice of varieties of bands with a focus on the influence of that sublattice on the structure of the whole lattice. The book concludes with the remarkable theorem due to Polak describing the whole lattice of varieties of completely regular as a subdirect product of lattices, some of which are well understood. The authors include recent advancements, insights, results, and techniques throughout the book.
