Abstract

In this paper, which is a sequel to an earlier paper, we consider special examples, methods, and invariants for the isomorphism problem for ordered dimension groups built on square primitive integer matrices A. We use the algorithm of our first paper to derive techniques and computable invariants for deciding isomorphism for subclasses of the matrices A.
