D. Senthilkumar, D. Kiruthika*

Abstract

Let be a - quasiposinormal operator on a complex Hilbert space, i.e for a positive integer, some and a positive integer. In this paper, we prove Browder's, Generalized Browder's, - Browder's and GeneralizedBrowder's theorem for- quasiposinormal operators.

Keywords

Weyl's theorem, - quasiposinormal operator, Riesz idempotent, generalized a - Weyl's theorem, B - Fredholm, B – Weyl.
