Embedding of Toeplitz operators with smooth symbols into strongly continuous semigroups

Emmanuel Fricain, Sophie Grivaux, Maëva Ostermann +1

Using the model theory for Toeplitz operators with smooth symbols developed by the fourth author in the 80's, we study whether such operators $T_{F}$ can be embedded into a $C_{0}$ …

The Cowen-Douglas class and de Branges-Rovnyak spaces

Emmanuel Fricain, Jaydeb Sarkar

We establish a connection between the de Branges-Rovnyak spaces and the Cowen-Douglas class of operators which is associated with complex geometric structures. We prove that the ba…

Hypercyclicity of Toeplitz operators with smooth symbols

Emmanuel Fricain, Sophie Grivaux, Maëva Ostermann

This paper is devoted to the study of the dynamics of Toeplitz operators $T_{F}$ with smooth symbols $F$ on the Hardy spaces of the unit disk $H^{p}$ , $p > 1$ . Building on a model theory…
