Abstract : In this paper we study some properties of the joint Weyl and Browder spectra for the slightly larger classes containing doubly commuting $n$-tuples of hyponor\-mal operators.
Keywords : hyponormal operator, $M$-hyponormal operators, $p$,hyponormal operator, joint Weyl spectrum, joint Browder spectrum
