What is it about?
Hardy’s uncertainty principle for the Gabor transform is proved for locally compact abelian groups having noncompact identity component and groups of the form Rn×K , where K is a compact group having irreducible representations of bounded dimension. We also show that Hardy’s theorem fails for a connected nilpotent Lie group G which admits a square integrable irreducible representation. Further, a similar conclusion is made for groups of the form G×D , where D is a discrete group.
