Approximation numbers of composition operators on the Hardy space of the ball and of the polydisk
Daniel Li, Hervé Queffélec, Luis Rodríguez-Piazza
We give general estimates for the approximation numbers of composition operators on the Hardy space on the ball and the polydisk .
Compact composition operators with non-linear symbols on the space of Dirichlet series
Frédéric Bayart, Ole Fredrik Brevig
We investigate the compactness of composition operators on the Hardy space of Dirichlet series induced by a map , where is a Dirichlet polynomial. Our resul…
Resolution of Peller's problem concerning Koplienko-Neidhardt trace formulae
Clément Coine, Christian Le Merdy, Denis Potapov +2
A formula for the norm of a bilinear Schur multiplier acting from the Cartesian product of two copies of the Hilbert-Schmidt classes into the trac…
Common hypercyclic vectors for high dimensional families of operators
Frédéric Bayart
Let be a family of operators acting on a -space , where the parameter space is a subset of . We give sufficient conditions on the family to…
