On the Jacobs-de Leeuw-Glicksberg decomposition for representations of semigroups
Micky Barthmann, Sohail Farhangi, Yulia Kuznetsova
We develop a systematic study of the Jacobs-de Leeuw-Glicksberg decomposition for JdLG-admissible semigroup representations on Banach spaces, with emphasis on its structural, ergod…

Uniform vector-valued pointwise ergodic theorems for operators
Micky Barthmann, Sohail Farhangi
We prove a uniform vector-valued Wiener-Wintner Theorem for a class of operators that includes compositions of ergodic Koopman operators with contractive multiplication operators.…
