Starting from the study of pseudodifferential operators with completely periodic symbols, we obtain results of continuity and invertibility of a class of Gabor operators on time-frequency invariant Banach spaces. As an application, we find sufficient conditions for the existence of Gabor frames on L^2, associated with a general lattice LZ^{2d}, where L is an invertible square matrix.

Abstract
Starting from the study of pseudodifferential operators with completely periodic symbols, we obtain results of continuity and invertibility of a class of Gabor operators on time-frequency invariant Banach spaces. As an application, we find sufficient conditions for the existence of Gabor frames on L^2, associated with a general lattice LZ^{2d}, where L is an invertible square matrix.File in questo prodotto:
