Besov regularity in non-linear generalized functions
Stevan Pilipović, Dimitris Scarpalézos, Jasson Vindas
We introduce and study new modules and spaces of generalized functions that are related to the classical Besov spaces. Various Schwartz distribution spaces are naturally embedded i…

Characterisation of the Weyl-Hörmander classes by time-frequency shifts
Stevan Pilipović, Bojan Prangoski
We characterise the Weyl-Hörmander symbol classes via the growth of the action of the corresponding DOs on time-frequency shifts of a single test function. For this pur…
