Completeness of uniformly discrete translates in $L^p(\mathbb{R})$ (2401.15588v2)

Abstract: We construct a real sequence ${\lambda_n}_{n=1}^{\infty}$ satisfying $\lambda_n = n + o(1)$, and a Schwartz function $f$ on $\mathbb{R}$, such that for any $N$ the system of translates ${f(x - \lambda_n)}$, $n > N$, is complete in the space $L^p(\mathbb{R})$ for every $p>1$. The same system is also complete in a wider class of Banach function spaces on $\mathbb{R}$.
