Lattice Packing of Spheres in High Dimensions Using a Stochastically Evolving Ellipsoid
Boaz Klartag
2:00pm|Simonyi 101

We prove that in any dimension n there exists an origin-symmetric ellipsoid of volume c n^2 that contains no points of Z^n other than the origin. Here c > 0 is a universal constant. Equivalently, there exists a lattice sphere packing in R^n whose...

Workshop on Recent Developments in Hodge Theory and O-minimality

10:00am|Simonyi Hall 101

Sponsored by Dr. John P. Hempel 

Organizer: Jacob Tsimerman

We will focus on recent developments in Hodge theory, which has emerged as both a unifying framework and powerful tool for problems in arithmetic and unlikely intersections. The goal will...

Ax-Schanuel and the Rank One Riemann-Hilbert Correspondence
Jonathan Pila
10:45am|Simonyi Hall 101

Abstract: A result of Simpson characterizes subspaces that are (irreducible) algebraic varieties on both sides of the rank one Riemann-Hilbert correspondence. This result suggests an underlying Ax-Schanuel statement. In joint work with Jacob...
