Quadratic Lattices: Properties and Equidistribution

This lecture discusses non-degenerate quadratic lattices, their properties, and equidistribution. It covers the existence of finite sets of integers related to quadratic lattices, local representability, and the Hermite-Minkowski theorem. The lecture also explores the duality principle, equidistribution in the genus, and the Siegel theorem for non-degenerate quadratic lattices in multiple variables.
