Title:
Stability theorems and sets of sampling in shift invariant subspaces of Lp
Abstract:
We prove new stability theorems for Gabor fames and for translation-invariant subspaces of Lp.
We also investigate non-uniform sets of sampling and sets of uniqueness in translation-invariant subspaces of Lp.
Our results improve theorems of Aldroubi and Grochenig. This is a joint work with P. Vellucci (Univ. Roma "La Sapienza")
