The Congruences Of A Finite Lattice

In the past half-century the study of lattices has become a large and important field with a great number of interesting and deep results and many open problems. One of the world's leading experts in lattice theory, George Grdtzer, presents major results on the subject in a self-contained exposition featuring the author's "Proof by Picture" method. Key features: * Discussion of the techniques used to construct "nice" lattices and "nice" congruence-preserving extensions * Use the of author's signature "Proof by Picture" method * Appendix featuring complete proofs * Good bibliography and index The book is appropriate for a one-semester graduate course, and will also be of interest to researchers studying lattices.
