Factorizations for quasi-Banach time-frequency spaces and Schatten classes
Divyang Bhimani, Joachim Toft
We deduce factorization properties for a quasi-Banach module over a quasi-Banach algebra. Especially we extend a result by Hewitt and prove that if any such algebra which possess a…

Pseudo-differential calculi and entropy estimates with Orlicz modulation spaces
Anupam Gumber, Nimit Rana, Joachim Toft +1
We deduce continuity properties for pseudo-differential operators with symbols in Orlicz modulation spaces when acting on other Orlicz modulation spaces. In particular we extend we…

Schatten-von Neumann properties for Hörmander classes on compact Lie groups
Duván Cardona, Marianna Chatzakou, Michael Ruzhansky +1
Let be a compact Lie group of dimension In this work we characterise the membership of classical pseudo-differential operators on in the trace class ideal $S_{1}(L^2(G…
