Upper bounds of numerical radius and $a$ -numerical radius in $C^{*}$ -algebra setting using Orlicz functions

Saikat Mahapatra, Riddhick Birbonshi, Arnab Patra

In this paper, several significant upper bounds for the numerical radius and $a$ -numerical radius of an element in a $C^{*}$ -algebra are obtained using Orlicz functions. Ma…

Joint $q$ -Numerical Ranges of Operators in Hilbert and Semi-Hilbert Spaces

Kais Feki, Arnab Patra, Jyoti Rani +1

This paper introduces and investigates the concept of the $q$ -numerical range for tuples of bounded linear operators in Hilbert spaces. We establish various inequalities concerning…
