Compactification and decompactification by weights on Bergman spaces

Pascal Lefèvre, Daniel Li, Hervé Queffélec +1

We characterize the symbols for which there exists a weight w such that the weighted composition operator M w C is compact on the weighted Bergman space B 2 . We also ch…

Boundedness of composition operators on general weighted Hardy spaces of analytic functions

Pascal Lefèvre, Daniel Li, Hervé Queffélec +1

We characterize the (essentially) decreasing sequences of positive numbers = ( n) for which all composition operators on H 2 () are bounded, where H 2 () is the space…

Average radial integrability spaces of analytic functions

Tanausu Aguilar-Hernandez, Manuel D. Contreras, Luis Rodriguez-Piazza

In this paper we introduce the family of spaces , . They are spaces of holomorphic functions in the unit disc with average radial integrability. Thi…

Comparison of singular numbers of composition operators on different Hilbert spaces of analytic functions

Hervé Queffélec, Pascal Lefèvre, Daniel Li +1

We compare the rate of decay of singular numbers of a given composition operator acting on various Hilbert spaces of analytic functions on the unit disk $\D$. We show that for the…

Compactification, and beyond, of composition operators on Hardy spaces by weights

Pascal Lefèvre, Daniel Li, Hervé Queffélec +1

We study when multiplication by a weight can turn a non-compact composition operator on H 2 into a compact operator, and when it can be in Schatten classes. The q-summing case in H…

Approximation numbers of composition operators on the Hardy space of the infinite polydisk

Daniel Li, Hervé Queffélec, L Rodríguez-Piazza

We study the composition operators of the Hardy space on D {\ell} 1 , the {\ell} 1 part of the infinite polydisk, and the behavior of their approximation numbers.
