He is best known for his work in lattice theory.

Ideals are of great importance for many constructions in order and lattice theory.

He worked mostly in lattice theory and universal algebra.

See the references in the entries order theory and lattice theory.

We now define some order-theoretic notions of importance to lattice theory.

The main idea is expressed in lattice theory.

Lattice theory captures the mathematical structure of order relations.

A third, equivalent way of describing the same class of objects uses lattice theory.

He is interested in category theory and lattice theory.

His early research was devoted to a fledgling branch of algebra based on what is now known as the lattice theory.

In this context, especially in lattice theory, greatest lower bounds are also called meets.

Mathematical morphology, theoretical model based on Lattice theory, used for digital image processing.

The absorption law is the only defining identity that is peculiar to lattice theory.

It corrects the starting point of lattice theory during the development of formal logic in 19th century.

It is a basic fact of lattice theory that the above condition is equivalent to its dual:

The mathematical basis, however, was already created by Garrett Birkhoff in the 1930s as part of the general lattice theory.

Since the two definitions are equivalent, lattice theory draws on both order theory and universal algebra.

Bottom element in lattice theory.

In lattice theory, 0 may denote the bottom element of a bounded lattice.

This is about lattice theory.

Filters appear in order and lattice theory, but can also be found in topology whence they originate.

Regrettably, it is often the case that standard treatments of lattice theory define a semilattice, if that, and then say no more.

Lattice Theory.

"Lattice theory: first concepts and distributive lattices."

Least upper bounds are important concepts in order theory, where they are also called joins (especially in lattice theory).
