Abstract

Consider the discrete maximal function acting on finitely supported functions on the integers, CΛf(n):=supλΛp±Pf(np)logpe2πiλpp, \mathcal{C}_\Lambda f(n) := \sup_{\lambda \in \Lambda} | \sum_{p \in \pm \mathbb{P}} f(n-p) \log |p| \frac{e^{2\pi i \lambda p}}{p} |, where ±P:={±p:p is a prime}\pm \mathbb{P} := \{ \pm p : p \text{ is a prime} \}, and Λ[0,1]\Lambda \subset [0,1]. We give sufficient conditions on Λ\Lambda, met by (finite unions of) lacunary sets, for this to be a bounded sublinear operator on p(Z)\ell^p(\mathbb{Z}) for 32<p<4\frac{3}{2} < p < 4.
