A Fejér theorem for boundary quotients arising from algebraic dynamical systems

Abstract
A Fejér-type theorem is proved within the framework of -algebras associated with certain irreversible algebraic dynamical systems. This makes it possible to strengthen a result on the structure of the relative commutant of a family of generating isometries in a boundary quotient.
