Abstract
In this paper we show that the spectrum is continuous on the class of ${\star}$-paranormal operators but the approximate point spectrum generally is not continuous at ${\star}$-paranormal operators.
Keywords
spectral continuity; single valued extension property; Kato's type; quasitriangular; ${\star}$-paranormal;
