This is a survey of work in which the author was involved in recent years. We consider C∗-algebras constructed from representations of one or several algebraic endomorphisms of a compact abelian group-or, dually, of a discrete abelian group. In our surveywe do not try to describe the entire scope of themethods and results obtained in the original papers, but we concentrate on the important thread coming from the action of the multiplicative semigroup of the ring of integers in an algebraic number field, or more generally of a Dedekind ring, on its additive group. Representations of such actions give rise to particularly intriguing problems and the study of the corresponding C∗-algebras has motivated many of the new methods and general results obtained in this area.
