Browder’s Theorem For Totally Posinormal Operators
In our study we consider a higher class of Hilbert space operators,Posinormal operators introduced by C. Rhaly (1992).We show that if T is a totally Posinormal operator such that T possesses property(ab), then Browder's theorem and generalized Browder’s theorem holds for T and for T+N where N is a nilpotent operator that commutes with T.

A-browder’s Theorem For Conditionally Totally Posinormal Operators
In this paper we present results on Browder's theorem for conditionally totally posinormal operators using established results on kato type operators and polaroid operators.
