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.
