摘要
We characterize the bounded linear operators T satisfying generalized alpha-Browder's theorem, or generalized alpha-Weyl's theorem, by means of localized SVEP, as well as by means of the quasi-nilpotent part H-0(lambda I-T) as lambda belongs to certain sets of C. In the last part we give a general framework in which generalized alpha-Weyl's theorem follows for several classes of operators.
