Stronger Cell Probe Lower Bounds via Local PRGs
Oliver Korten
11:00am|Simonyi Hall 101 and Remote Access

In this work, we develop a new method for proving lower bounds for static data structures in the classical cellprobe model of Yao. Our methods give the strongest known lower bounds for any explicit problem in this model (quadratically stronger for...

Special Joint IAS/PU Symplectic Geometry Seminar

A Poincaré-Birkhoff theorem for $C^0$-Hamiltonian maps
Agustin Moreno
4:30pm|Simonyi Classroom (S-114)

In this talk, I will present a proof of a Poincaré--Birkhoff theorem for Hamiltonian maps on Liouville domains which are only continuous at the boundary. The motivation is finding periodic orbits in the circular, restricted three-body problem. Based...

The Intersection of Modular Correspondence
Baiqing Zhu
3:30pm|Fine 110, Princeton University

In this talk, I will present recent work on the intersection theory of modular correspondences. Specifically, we study the intersection numbers of modular correspondences of square-free level, focusing both on the nonsingular intersections and the...
