Operators commuting with complex symmetric weighted composition operators on H 2

open access: yesConcrete Operators
In this article, we initially study when an anti-linear Toeplitz operator is in the commutant of a composition operator. Primarily, we investigate weighted composition operators Wg,ψ{W}_{g,\psi } commuting with complex symmetric weighted composition ...

Composition operators with surjective symbol and small approximation numbers

open access: yes, 2018
We give a new proof of the existence of a surjective symbol whose associated composition operator on H 2 (D) is in all Schatten classes, with the improvement that its approximation numbers can be, in some sense, arbitrarily small.

Norms and essential norms of composition operators from H to general weighted Bloch spaces in the polydisk

open access: yesJournal of Inequalities and Applications, 2011
Let Un be the unit polydisk of ℂ n and φ a holomorphic self-map of Un. H∞(Un) and B log α ( U n ) denote the space of bounded holomorphic functions and the space of general weighted Bloch functions ...
