Abstract
In this paper, two stability results regarding exponential frames are compared. The theorems, (one proven herein, and the other in Sun and Zhou (J. Math. Anal. Appl. 235:159–167, 1999)), each give a constant such that if \({\sup }_{n\in {\mathbb{Z}}^{}}\|{\epsilon {}_{n}\|}_{\infty } < C\), and (ei⟨ ⋅,t n ⟩) n∈ℤ d is a frame for L 2[−π,π]d, then (ei⟨ ⋅,t n +ε n ⟩) n∈ℤ d is a frame for L 2[−π,π]d. These two constants are shown to be asymptotically equivalent for large values of d.
