A trace inequality for non-commuting hyponormal tuples
International Journal of Mathematical Analysis, 2022We introduce the class of almost right hyponormal and almost jointly hyponormal multi-operators and give a sufficient condition for some “commutator” associated to such multi-operators to belong to the trace class.

On unitary invariance of some classes of operators in Hilbert spaces
, 2020It is a known fact in operator theory that two similar operators have equal spectra but they do not necessarily have to belong to the same class of operators.

Let $H$ be a separable complex Hilbert space and let $B(H)$ denote the algebra of all bounded linear operators on $H.$ If $T$ is a quasi-normal Fredholm operator we prove that $TT^*\in (QD)(P_n)$ if and only if $T^*T\in (QD)(P_n).$ We also show that if ...
