Query: Operator algebras associated to integral domains   We study operator algebras associated to integral domains. In particular,
with respect to a set of natural identities we look at the possible
nonselfadjoint operator algebras which encode the ring structure of an integral
domain. We show that these algebras give a new class of examples of semicrossed
products by discrete semigroups. We investigate the structure of these algebras
together with a particular class of representations.
