Approximation numbers of composition operators on the Hardy space of the infinite polydisk
(Springer, 2017-12)We study the composition operators of the Hardy space on D∞ ∩ℓ1, the ℓ1 part of the infinite polydisk, and the behavior of their approximation numbers.

Compactification, and beyond, of composition operators on Hardy spaces by weights
(OJS/PKP, 2021-06-08)We study when multiplication by a weight can turn a non-compact composition operator on H2 into a compact operator, and ...
