Weyl-Heisenberg frames for subspaces of L^2(R)

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/77758We give sufficient conditions for translates and modulates of a function g in L^2(R) to be a frame for its closed linear span. Even in the case where this family spans all of L^2(R), wou conditions are significantly weaker than the previous known conditions.13 pagesFunctional Analysis42C15; 46C05; 46B20Weyl-Heisenberg frames for subspaces of L^2(R)text
