Pseudodifferential Operators on Weighted Hardy Spaces

Generalized composition operators on weighted Hardy spaces

Pseudodifferential operators and weighted normed symbol spaces

In this work we study some general classes of pseudodifferential operators where the classes of symbols are defined in terms of phase space estimates. Résumé On étudie des classes générales d’opérateurs pseudodifférentiels dont les classes de symboles sont définis en termes d’éstimations dans l’espace de phase.

Norms of Composition Operators on Weighted Hardy Spaces

The norm of a bounded composition operator induced by a disc automorphism is estimated on weighted Hardy spaces H(β) in which the classical Hardy space is continuously embedded. The estimate obtained is accurate in the sense that it provides the exact norm for particular instances of the sequence β. As a by-product of our results, an estimate for the norm of any bounded composition operator on ...
