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 later. Since the …

George Grätzer started writing his General Lattice Theory in 1968. It was published in 1978.
It set out “to discuss in depth the basics of general lattice theory.” Almost 900 exercises, 193 …

Gautama algebras were introduced recently, as a common generalization of regular double
Stone algebras and regular Kleene Stone algebras. Even more recently, Gautama algebras …

Let $ V $ be a congruence distributive variety, or a congruence modular variety whose free
algebra on 2 generators is finite. If $ V $ is residually small and has the amalgamation …

In this chapter we discuss some of the more recent results and give a general overview of
what is currently known about lattice varieties. Of course it is impossible to give a …

A variety $\mathcal {V} $ has a cofinal set $ S\subset\mathcal {V} $ if any $ A\in\mathcal {V} $
is embeddable in a reduced product of members of $ S $. Amalgamation in and examples of …
