We characterize the bounded linear operators $T$ satisfying generalized $a$-Browder's theorem, or generalized $a$-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 $\mathbb C$. In the last part we give a general framework in which generalized $a$-Weyl's theorem follows for several classes of operators.
