On the convexity of Berezin range and Berezin radius inequalities via a class of semi-norms

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

This paper introduces a new family of semi-norms, say $σ_{μ}$ -Berezin norm on the space of all bounded linear operators $B (H)$ defined on a reproducing kernel Hilbert space…

A Family of Semi-norms in $C^{*}$ -algebras

Athul Augustine, Pintu Bhunia, P. Shankar

We introduce a new family of non-negative real-valued functions on a $C^{*}$ -algebra $A$ , i.e., for $0 \leq μ \leq 1,$ $$\|a\|_{σ_μ}= \text{sup}\left\lbrace \sqrt{|f(a)|^2 σ_…

Composition operators between Beurling subspaces of Hardy space

V. A. Anjali, P. Muthukumar, P. Shankar

V. Matache (J. Operator Theory 73(1):243--264, 2015) raised an open problem about characterizing composition operators $C_{ϕ}$ on the Hardy space $H^{2}$ and nonzero singular measures…
