Title:​ Lattice points in symmetric bodies.

Abstract: In a lattice point problem we are interested in estimating the number of points with integer coordinates lying inside a certain subregion of $\mathbb{R}^n$ depending on a parameter, as the parameter becomes large. Usually this family of regions correspond to dilations of a single convex body. We will see that Fourier analysis (in particular Poisson's summation formula) and exponential sums play a key role in this kind of problems. Extra symmetries can often be exploited to obtain better bounds for the error term, but technical conditions might arise.
