Abstract.   The aim of this paper is to introduce new spectral properties as a continuation of the papers [8], [9], [11], [16], which are variants to the classical a-Browder's and Browder's theorem and we study the relationship between these properties and other Weyl-type theorems.

Keywords:  Browder's theorem; a-Browder's theorem; property (b).
