$q$-Berezin Range of Operators in Hardy Space

Functional Analysis 2026-05-06 v2

Abstract

This paper investigates the concept of the qq-Berezin range and qq-Berezin number of bounded linear operators acting on Hardy space. We obtain the qq-Berezin range of some classes of operators on Hardy space. In addition, the convexity of the qq-Berezin range is explored for finite-rank, diagonal, multiplication, weighted shift, and certain composition operators.
