The Congruences of a Finite Lattice

The congruences of a lattice form the congruence lattice.  Over the last several decades, the study of congruence lattices has established itself as a large and important field with a great number of interesting and deep results, as well as many open problems.  Written by one of the leading experts in lattice theory, this text provides a self-contained introduction to congruences of finite lattices and presents the major results of the last 90 years.  It features the author's signature "Proof-by-Picture" method, which is used to convey the ideas behind formal proofs in a visual, more intuitive manner.  Key features include: This text is appropriate for a one-semester graduate course in lattice theory, and it will also serve as a valuable reference for researchers studying lattices.  Reviews of previous editions: "[This] monograph...is an exceptional work in lattice theory, like all the contributions by this author. The way this book is written makes it extremely interesting for the specialists in the field but also for the students in lattice theory.  -- Cosmin Pelea, (1), 2007 "The book is self-contained, with many detailed proofs presented that can be followed step-by-step. I believe that this book is a much-needed tool for any mathematician wishing a gentle introduction to the field of congruences representations of finite lattices, with emphasis on the more 'geometric' aspects."   -- Mathematical Reviews
