Littlewood's problem for sets with multidimensional structure

Abstract

We give L1L^1-norm estimates for exponential sums of a finite sets AA consisting of integers or lattice points. Under the assumption that AA possesses sufficient multidimensional structure, our estimates are stronger than those of McGehee-Pigno-Smith and Konyagin. These theorems improve upon past work of Petridis.
