New classes of hypercyclic Toeplitz operators
We study hypercyclicity of Toeplitz operators in the Hardy space
with symbols of the form , where

operators and give new sufficient conditions for hypercyclicity based on deep

NEW CLASSES OF HYPERCYCLIC TOEPLITZ OPERATORS
International audienceWe study hypercyclicity of Toeplitz operators in the Hardy space H 2 (D) with symbols of the form R(z) + ϕ(z), where R is a rational function and ϕ ∈ H ∞ (D). We relate this problem to cyclicity of certain families of functions for analytic Toeplitz operators and give new sufficient conditions for hypercyclicity based on deep results of B. Solomyak
