Singular inner eigenfunctions of composition operators
V. A. Anjali, P. Muthukumar, P. Shankar
This paper characterizes all the singular inner eigenfunctions of the composition operators that arise from discrete measures, when is an automorphism of unit disk. By es…
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 -Berezin norm on the space of all bounded linear operators defined on a reproducing kernel Hilbert space…
A Family of Semi-norms in -algebras
Athul Augustine, Pintu Bhunia, P. Shankar
We introduce a new family of non-negative real-valued functions on a -algebra , i.e., for $$\|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 on the Hardy space and nonzero singular measures…
