On posinormality of weighted composition-differentiation operators on $H^{2} (D)$

Gour Hait, Sarita Ojha, Nirupam Ghosh +1

In this article, the posinormality and coposinormality of weighted composition-differentiation operators on Hardy space $H^{2} (D)$ are investigated. It is observed that whil…

Invariant subspaces of idempotents on Hilbert spaces

Neeru Bala, Nirupam Ghosh, Jaydeb Sarkar

In the setting of operators on Hilbert spaces, we prove that every quasinilpotent operator has a non-trivial closed invariant subspace if and only if every pair of idempotents with…
