Title: | Wave-front sets in fourier lebesgue spaces | Authors: | Pilipović, Stevan Teofanov, Nenad Toft J. |
Issue Date: | 1-Dec-2008 | Journal: | Rendiconti del Seminario Matematico | Abstract: | We consider wave-front sets in the framework of weighted Fourier Lebesgue spaces, f Lqs. We prove that (*) WFf Lqs-m (Af) ⊂ WFf Lqs (f) ⊂ WF f Lqs-m (Af) ∪ Char A where A is properly supported pseudo-differential operator of order m and Char A denotes the set of characteristic points of A. Moreover, we discuss more general class of pseudo-differential operators in the framework of modulation spaces and present (*) in a more general setting. | URI: | https://open.uns.ac.rs/handle/123456789/10915 | ISSN: | 03731243 |
