Abstract

In this paper we define new spectral properties$(h)$, $(gh)$, $(ah)$ and $(gah)$ as a continuation of [H.Zariouh, Property (gz) for bounded linear operators, Mat. Vesnik,65 (2013), 94–103], which are variants to the properties $(z)$,$(gz)$ and $(az)$ introduced in the mentioned paper. The purposeof the paper is to study the relationship between these propertiesand other Weyl-type theorems.
