Wave-front sets in non-quasianalytic setting for Fourier Lebesgue and modulation spaces
We define and study wave-front sets for weighted Fourier-Lebesgue spaces when
the weights are moderate with respect to the associated functions for general
sequences which satisfy Komatsu's conditions . In
particular, when is the Gevrey sequence (, ) we
recover some previously observed results. Furthermore, we consider wave-front
sets for modulation spaces in the same setting, and prove the invariance
property related to the Fourier-Lebesgue type wave-front sets.Comment: 30 pages. arXiv admin note: text overlap with arXiv:1806.0440
