Abstract

A power partial isometry (PPI) is an element v of a C^*-algebra with the property that every power vⁿ is a partial isometry. The goal of this paper is to identify the universal C^*-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 Böttcher and Bernd Silbermann in 1983.
