484anisotropic modulation spaces
- Mar 27, 2011I am trying to define anisotropic modulation spaces because a professor give a lecture about an operator which can be generalized if we have anisotropic modulation spaces. But it seems impossible since the composition of a diagonal matrix and a translation(since we define modulation spaces by decompositing the frequency space) will introduce some problem that cannot be overcome. Can you give a way to solve it? Thanks!
