Convexity of the Berezin range of operators on
Sandip Kumar Maiti, Satyajit Sahoo, Gorachand Chakraborty
In this paper, we characterize the convexity of the Berezin range for finite-rank operators acting on the weighted Hardy space over the unit disc $\mat…
Generalized complex symmetric composition operators with applications
Vasudevarao Allu, Satyajit Sahoo
We characterize the weighted composition-differentiation operators $D_{\mfn,Ï,Ï}$ acting on over the polydisk which are complex symm…
Some spectral properties and convergence of the -numerical radius and -Crawford number
Pembe Ipek Al, Zameddin I. Ismailov, Fuad Kittaneh +1
In this study, some estimates are given for the -numerical radius and -Crawford number via the -numerical radius and -Crawford number for the -bounded…
Further bounds on -numerical radii of operators via generalized Aluthge transform
Satyajit Sahoo
The main aim of this article is to establish several -numerical radius inequalities via the -Aluthge transform of Hilbert space operators and operator matrices. Furthermo…
On inequalities involving the spherical operator transforms
Fuad Kittaneh, Satyajit Sahoo, Hranislav StankoviÄ
This paper explores refinements of some operator norm inequalities through the generalized spherical Aluthge transform and the spherical Heinz transform. We introduce the spherical…
