Abstract

Let be the universal -algebra generated by a semigroup of isometries whose range projections commute. We analyse the structure of KMS states on for the time evolution determined by a homomorphism. In contrast to the reduced version, we show that the set of KMS states on has a rich structure. In particular, we exhibit uncountably many extremal KMS states of type I, II and III.
