The study of lattice varieties is a field that has experienced rapid growth in the last 30 years, but many of the interesting and deep results discovered in tha

This book is the second of a three-volume set of books on the theory of algebras, a study that provides a consistent framework for understanding algebraic syste

The book is meant to serve two purposes. The first and more obvious one is to present state of the art results in algebraic research into residuated structures

It is shown that there are eight infinite sequences of join irreducible lattice varieties with the following properties: each term of every sequence has the nex

This book started with Lattice Theory, First Concepts, in 1971. Then came General Lattice Theory, First Edition, in 1978, and the Second Edition twenty years la
