Sharp embedding between Besov-Triebel-Sobolev spaces and modulation spaces
arXiv:2108.12106
Abstract
The embedding relations between Besov-Triebel-Sobolev spaces and modulation spaces are determined explicitly. We extend the results of Sugimoto[2007]; Wang[2007] and Kobayashi[2011] to the most general cases. And we give the sharp embedding between Fourier spaces and modulation spaces.
