Lattice theory is the study of sets of objects known as Lattices. It is an outgrowth of the study of Boolean Algebras, and provides a framework for unifying the study of classes or ordered sets in mathematics. Its study was given a great boost by a series of papers and subsequent textbook written by Birkhoff (1967).
