A survey of semimodularity that presents theory and applications in discrete mathematics, group theory and universal algebra.In Semimodular Lattices, Manfred Stern uses successive generalizations of distributive and modular lattices to outline the development of semimodular lattices from Boolean algebras. He focuses on the important theory of semimodularity, its many ramifications, and its applications in discrete mathematics, combinatorics, and algebra. The book surveys and analyzes Garrett Birkhoff's concept of semimodularity and the various related concepts in lattice theory, and it p resents theoretical results as well as applications in discrete mathematics group theory and universal algebra. Researchers in lattice theory, discrete mathematics, combinatorics, and algebra will find this book valuable.In Semimodular Lattices, Manfred Stern uses successive generalizations of distributive and modular lattices to outline the development of semimodular lattices from Boolean algebras.
