These are the Hardy-Littlewood majorant problem, and L2n(T), n is an element of N norms of exponential sums, which can also be interpreted as solutions of diophantine equations or lattice points on surfaces. We establish connections to the well known problems on lattice points in regions such as the Dirichlet divisor problem. (c) 2025 Elsevier Inc.
