Fourier uniqueness pairs of powers of integers

Classical Analysis and ODEs 2019-10-11 v1

Abstract

We prove, under certain conditions on (α,β)(\alpha,\beta), that each Schwartz function ff such that f(±nα)=f^(±nβ)=0,n0f(\pm n^{\alpha}) = \hat{f}(\pm n^{\beta}) = 0, \forall n \ge 0 must vanish identically, complementing a series of recent results involving uncertainty principles, such as the pointwise interpolation formulas by Radchenko and Viazovska and the Meyer-Guinnand construction of self-dual crystaline measures.
