Abstract

A power partial isometry (PPI) is an element vv of a CC^*-algebra with the property that every power vnv^n is a partial isometry. The goal of this paper is to identify the universal CC^*-algebra generated by a PPI with (a slight modification of) the algebra of the finite sections method for Toeplitz operators with continuous generating function, as first described by Albrecht B\"ottcher and Bernd Silbermann in 1983.
