Local Fourier Bases and Ultramodulation Spaces
local Fourier Ultramodulation Spaces ultramodulation spaces
2010/2/25
It was proved that local Fourier bases are unconditional bases for modulation spaces Mp.qw. We prove that the local Fourier bases are unconditional bases for ultramodulation spaces Mpwg=Mp.pwg, where ...

local Fourier bases Schur test nixed norm space atomic decomposition
2010/2/26
It is shown that local Fourier bases are unconditional bases for modulation spaces. We prove first a version of the Schur test for double sequence with mixed norm and then use it to show boundedness o...
