Hyponormal Toeplitz operators with operator valued normal symbols

Neeru Bala, Pratima Pandey

In this article, we first give a characterization of hyponormal Toeplitz operators with operator valued normal symbols. Latter, we examine when the class of hyponormal Toeplitz ope…

Spectral Characterizations of Schatten-class perturbations of Partial isometries

Neeru Bala, Ramesh Golla

We characterize bounded operators that are compact (respectively, Schatten-class) perturbations of scalar multiples of partial isometries with finite-dimensional kernel. Our charac…

Hyponormal contractions and analytic shifts

Sneha B, Neeru Bala, Jaydeb Sarkar

Hyponormal operators are known to be among the most difficult operators to analyze. In this work, we focus on two finite types of hyponormal operators. The first type becomes analy…

The iterated Aluthge Transforms of compact operators

Neeru Bala

Let be a bounded linear operator on a Hilbert space. Then the Aluthge transform and the sequence of Aluthge iterates of are defined by \begin{align*} ΔT=|T|^{…

Liftings and invariant subspaces of Hankel operators

Sneha B, Neeru Bala, Samir Panja +1

We prove a Hankel-variant commutant lifting theorem. This also uncovers the complete structure of the Beurling-type reducing and invariant subspaces of Hankel operators. Kernel spa…

Norm attaining composition operators on Segal-Bargmann spaces

Neeru Bala, Sudip Ranjan Bhuia

In this note, we study the composition operators on Segal-Bargmann spaces, which attains its norm and we show that every composition operators on the classical Fock space over $\ma…
