Abstract
In this note, we give necessary and sufficient conditions for a system of complex exponentials {e(i lambda nt)} to form a Riesz-Fischer sequ ence in L-2(-A, A) for every positive number A. The result provides a significant strengthening of the sufficient conditions recently stated by R. M. Reid (1995).
