The task of looking for conditions under which two quasisimilar operators have equal spectra or essential spectra is quite evident in the extant literature of operator theory. However the case of equality of Weyl spectra for such operators is often overlooked. In this paper we strive to fill this gap by considering mainly the class of w- hyponormal operators and its subclasses. Download
