The theme of this book is an exposition of connections between
representations of finite partially ordered sets and abelian groups.
Emphasis is placed throughout on classification, a description of the
objects up to isomorphism, and computation of representation type, a
measure of when classification is feasible. David M. Arnold is the Ralph
and Jean Storm Professor of Mathematics at Baylor University. He is the
author of "Finite Rank Torsion Free Abelian Groups and Rings" published
in the Springer-Verlag Lecture Notes in Mathematics series, a co-editor
for two volumes of conference proceedings, and the author of numerous
articles in mathematical research journals.
