Convexity of Berezin Range and Berezin Radius Inequalities via a class of Seminorm

P. Hiran Das, Athul Augustine, Pintu Bhunia +1

Let denote the -algebra of all bounded linear operators acting on a reproducing kernel Hilbert space In this paper, we introduce a new famil…

Composition operators, convexity of their Berezin range and related questions

Athul Augustine, M. Garayev, P. Shankar

The Berezin range of a bounded operator acting on a reproducing kernel Hilbert space is the set := $\{\langle T\hat{k}_{x},\hat{k}_{x} \rangle_{\m…

On products of symmetries in von Neumann algebras

B V Rajarama Bhat, Soumyashant Nayak, P Shankar

Let be a type von Neumann algebra. We show that every unitary in may be decomposed as the product of six symmetries (that is, self-adjoint unitar…

Boundary Representations and Rectangular Hyperrigidity

Arunkumar C. S, Shankar P, A. K. Vijayarajan

We explore connections between boundary representations of operator spaces and those of the associated Paulsen systems. Using the notions of finite representation and separating pr…

Pairs of projections and commuting isometries

Sandipan De, Shankar. P, Jaydeb Sarkar +1

It is known that the non-zero part of compact defect operators of Berger-Coburn-Lebow pairs (BCL pairs in short) of isometries are diagonal operators of the form \[ \begin{bmatrix}…
