Abstract:In our recent characterization of completely bounded Fourier multipliers between H1 and H2 or H1 and BMOA spaces on torus, we introduce a notion of exact self-tensor stability (abbrev. ESTS) for a family of operators. In this talk, firstly, an efficient way of checking ESTS will be explained for a given family of unit norm Boolean matrices or Boolean operators, secondly, the Hankel operators associated with various monoids will be proved in various different ways to have ESTS. Many natural conjectures will also be given. The talk is based on joint work with Yong HAN and Zipeng WANG.
