Three problems on exponential bases
Abstract
We consider three special and significant cases of the following problem. Let D be a (possibly unbounded) set of finite Lebesgue measure in Rd. Find conditions on D for which the standard exponential basis on the unit cube of Rd is a frame, a Riesz sequence, or a Riesz basis on L2(D).
