In Appl. Comput. Harmon. Anal. 2 (1995), 160-173, Favier and Zalik presented a multivariate version of Kadec's 1/4-theorem. But their result contains an additional condition B d (L) < 1. In this paper, we show that this condition may be deleted. In fact, we make a straightforward generalization of K

โฆ Synopsis
In this paper, we study the stability of Gabor frames ฯ mb na m n โ Z . We show that ฯ mb na m n โ Z remains a frame under a small perturbation of ฯ m, or n. Our results improve some results from Favier and Zalik and are applicable to many frequently used Gabor frames. In particular, we study the case for which ฯ is not compactly supported, and, for the particular case of the Gaussian function, we give explicit stability bounds.

A Gabor system is a set of time-frequency shifts S(g, ) = {e 2ฯibx g(xa)} (a,b)โ of a function g โ L 2 (R d ). We prove that if a finite union of Gabor systems r k=1 S(g k , k ) forms a frame for L 2 (R d ) then the lower and upper Beurling densities of = r k=1 k satisfy D -( ) โฅ 1 and D + ( ) < โ.
We show the existence of a "best approximation solution" to the set of equations f, f i = a i , i โ I, where {f i } iโI is a frame for a Hilbert space (H, โข, โข ) and {a i } iโI โ l 2 (I). We derive formulas showing how the solution changes if {a i } iโI or {f i } iโI is perturbed. We explain why the
We consider two problems involving Gabor frames that have recently received much attention. The first problem concerns the approximation of dual Gabor frames in L 2 (R) by finite-dimensional methods. Utilizing the duality relations for Gabor frames we derive a method to approximate the dual Gabor fr
The Gabor scheme is generalized to incorporate several window functions as well as kernels other than the exponential. The properties of the sequence of representation functions are characterized by an approach based on the concept of frames. Utilizing the piecewise Zak transform (PZT), the frame op
