Topics

The conference will be focused on problems in the arithmetic theory of quadratic forms and lattices, as well as those on number fields (e.g., units, class numbers, totally real fields), and related topics from algebraic and analytic number theory, discrete geometry, and the geometry of numbers (including continued fractions and their generalizations). We continue the rich tradition of an informal conference series on these topics (see below).
