In this paper we give necessary and sufficient conditions for a bounded\nlinear operator T to be generalized Drazin-Riesz invertible or generalized\nDrazin-meromorphic invertible. Also, we study generalized Browder's theorem and\ngeneralized a-Browder's theorem by means of set of interior points of various\nparts of spectrum of T.\n
