- Abstract
Let T be a bounded linear operator on a complex Hilbert space H. In this paper we introduce a new class of operators: (n,k) -quasi class Q* operators, superclass of (n,k) -quasi- *-paranormal operators. An operator T is said to be (n,k) -quasi class Q* if it satisfies for all x ∈ H and for some nonnegative integers n and k. We will prove structural and spectral properties of this class of operators, and also prove the spectrum continuity of this class of operators.
