Discrete restriction estimates for forms in many variables

Cook, Brian; Hughes, Kevin; Palsson, Eyvindur

Abstract

We prove discrete restriction estimates for a broad class of hypersurfaces arising in seminal work of Birch. To do so, we use a variant of Bourgain’s arithmetic version of the Tomas–Stein method and Magyar’s decomposition of the Fourier transform of the indicator function of the integer points on a hypersurface.
