Cones of Noether-Lefschetz divisors and moduli of hyperkähler manifolds

Speaker: Laure Flapan, Michigan State University

Location: Warren Weaver Hall 512

Date: Tuesday, November 12, 2024, 3:30 p.m.

Synopsis:

We describe how to compute cones of Noether-Lefshetz divisors on orthogonal modular varieties with a particular view towards moduli spaces of polarized K3 surfaces and hyperkähler manifolds. We then describe some geometric applications of these cone computations for these moduli spaces. This is joint work with I. Barros, P. Beri, and B. Williams.
