More on Approximate OperatorsDOI: 10.4067/S0719-06462012000100009 Keywords: hilbert space, approximation, unitary, partial isometry, polar decomposition, p, )-approximate operator. Abstract: this note is a continuation of the work on (p; )-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 .
