In this paper we explore some characteristics of the quasi-Fredholm resolvent set $$\rho _{qf}(T)$$ ρ qf ( T ) of an operator T defined on an infinite dimensional Banach space X . Moreover, in the case of Hilbert space H , we study the stability of the SVEP and describe the operators for which the SVEP is preserved under compact perturbations using quasi-Fredholm spectrum and $$\rho _{qf}(T)$$ ρ qf ( T ) .
