Characterization of boundedness on Wiener amalgam spaces of multilinear Rihaczek distributions
Weichao Guo, Guoping Zhao
In this paper, we give several characterizations for the boundedness of multilinear Rihaczek distributions acting from Wiener amalgam spaces to modulation and Fourier modulation sp…

Boundedness and compactness kernel theorem for -modulation spaces
Guoping Zhao, Weichao Guo
This paper is devoted to establishing the kernel theorems for -modulation spaces in terms of boundedness and compactness. We characterize the boundedness of a linear operator $…
