%X 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 .
