QUASI SIMILARITY AND INJECTIVE p-QUASIHYPONORMAL OPERATORS
Woo, Young-Jin;

Abstract
In this paper it is proved that quasisimilar n-tuples of tensor products of injective p-quasihyponormal operators have the same spectra, essential spectra and indices, respectively. And it is also proved that a Weyl n-tuple of tensor products of injective p-quasihyponormal operators can be perturbed by an n-tuple of compact operators to an invertible n-tuple.
