Absolutely minimum attaining Toeplitz and absolutely norm attaining Hankel operators (2209.05841v1)
Published 13 Sep 2022 in math.FA
Abstract: In this article, we completely characterize absolutely norm attaining Hankel operators and absolutely minimum attaining Toeplitz operators. We also improve \cite[Theorem 2.1]{RGSSSTOE1}, by characterizing the absolutely norm attaining Toeplitz operator $T_\varphi$ in terms of the symbol $\varphi \in L\infty$.
