Abstract
This note is a continuation of the work on (p,є)–approximate operators studied by Mirzavaziri, Miura and Moslehian. [4]. We investigate approximate partial isometries and approximate generalized inverses. We also prove that if T is an invertible contraction satisfying . Then there exists a partial isometry V such that ‖T − V‖ < Kє for K > 0.
