Abstract Let T= U| T| be the polar decomposition of a bounded linear operator on a complex
Hilbert space. T is called a class p-wA (s, t) operator if {ie641-1} and {ie641-2} where 0< s, t …

Let T= U| T| be a polar decomposition of a bounded linear operator T on a complex Hilbert
space with ker U= ker| T|. T is said to be class p-wA (s, t) if (| T*| t| T| 2s| T*| t) tp s+t≥| T*| 2tp …

Let A and B be positive operators and 0< q≤ 1. In this paper, we shall show that if

In this work, we demonstrate that (i) if T is a class p-wA (s, t) operator and T (s, t) is
quasinormal (resp., normal), then T is also quasinormal (resp., normal)(ii) If T and T∗ are …

In this paper, we study Weyl type theorems for $ f (T) $, where $ T $ is algebraically class $ p
$-$ wA (s, t) $ operator with $0< p\leq 1$ and $0< s, t, s+ t\leq 1$ and $ f $ is an analytic …
