$k$ -quasi $n$ -power posinormal Weighted Composition and Cauchy Dual of Moore-Penrose inverse of Lambert Operators

Sophiya S Dharan, T. Prasad, P. Ramya +1

In this paper we characterize $k$-quasi $n$-power posinormal composition operators and weighted composition operators on the Hilbert space $L^2(Σ)$. For Lambert conditional o…

Asymmetric Fuglede-Putnam Theorem for Unbounded M-Hyponormal Operators

T. Prasad, E. Shine Lal, P. Ramya

A closed densely defined operator $T$ on a Hilbert space $H$ is callled $M$ -hyponormal if $D (T) \subset D (T^{*})$ and there exists $M > 0$ for…
