Hyponormality of the sum of two Toeplitz operators

Functional Analysis 2026-04-27 v1

Abstract

In this paper, we have studied the hyponormality and invertibility of the operator of type wTφ+TψwT_{\varphi}+T_{\psi} where ww is any non-zero complex number and Tφ,TψT_{\varphi}, T_{\psi} are Toeplitz operators. We have also studied hyponormality when the symbol of Toeplitz operator is a linear functional.
