On (α,β)-Class (Q) Operators
(International Journal of Mathematics and its Applications, 2021-01-12)
In this paper, we introduce a new class of operator, the class of (α, β)-Class (Q) operator acting on a complex Hilbert
space H. An operator T ∈ B(H) is said to be (α, β)-Class (Q) if α 2T∗2T 2 ≤ (T∗T) 2 ≤ β 2T ∗2T 2 for ...
Further Generalization of Unitary Quasi-Equivalence of Operators
(International Journal of Mathematics And its Applications, 2020-10-06)
In this paper, we further generalize the class of n-Unitary Quasi-Equivalence by extending this study to (n,m)-Unitary
Quasi-Equivalence. We investigate the properties of this class and also the relation of this equivalence ...
On N Quasi D-Operator Operators
(International Journal of Mathematics And its Applications, 2020-01-11)
: In this paper, we introduce the class of N quasi D-operator acting on the usual Hilbert space H over the complex plane.

On Class (Q )
(International Journal of Mathematics And its Applications, 2020-11-12)
Class (Q) operators was introduced and studied by Jibril in (quote). In this paper , we introduce and study the “cousins”
to this class, namely class (Q∗). An operator T ∈ B(H) is said to belong to class (Q∗) if T
