Nearly invariant subspaces and weighted dual truncated Toeplitz operators

Sudip Ranjan Bhuia

Let $M = h K_{u}$ be a nearly $S^{*}$ -invariant subspace of $H^{2}$ , where $K_{u} = H^{2} ⊖ u H^{2}$ and $h$ is the extremal multiplier. For $\vp\in L^\infty(\T)$,…

Algebraic characterizations of paired operators on model spaces

Sudip Ranjan Bhuia, Satyabrata Majee

We study paired multiplication operators associated with orthogonal decompositions of $L^{2} (T)$ arising from Hardy spaces and Sz.-Nagy--Foias model spaces. For a non-consta…

On the minimum modulus of dual truncated Toeplitz operators

Sudip Ranjan Bhuia, Ramesh Golla, Puspendu Nag

This article provides a systematic investigation of the minimum modulus of dual truncated Toeplitz operators (DTTOs) $D_{I ¨} $ acting on the orthogonal complement of the model space $…

Norm attaining dual truncated Toeplitz operators

Sudip Ranjan Bhuia, Puspendu Nag

This paper develops a complete framework for understanding when a dual truncated Toeplitz operator (DTTO) attains its norm. Given a nonconstant inner function $u$ , the DTTO associa…

Operators commuting with complex symmetric weighted composition operators on $H^{2}$

Sudip Ranjan Bhuia

In this paper, we initially study when an anti-linear Toeplitz operator is in the commutant of a composition operator. Primarily, we investigate weighted composition operators $W_{…
