Abstract
In this paper we consider two new variants of the classical Weyl ’s theorem for operators defined on Banach spaces. These variants called S-Weyl’s theorem and property (t) are stronger than the more classical variants of Weyl’s theorem, as a-Weyl’s theorem and property (ω) studied by several authors. In particular, we explore these two new variants for operators that commute with an injective quasi-nilpotent operators
