Integral Points On The Clebsch-Klein Surfaces
Rafael von Känel
4:30pm|Fine Hall 214, Princeton University

In this talk we present explicit bounds for the Weil height and the number of integral points on classical surfaces first studied by Clebsch (1871) and Klein (1873). Building on Hirzebruch's work in which he related these surfaces to a Hilbert...

What is Combinatorial Discrepancy?
Peng Zhang
1:00pm|Simonyi 101 and Remote Access

Combinatorial discrepancy asks the following question: Given a ground set U and a collection S of subsets of U, how do we color each element in U red or blue so that each subset in S has almost an equal number of each color? A straightforward idea is...

Private Optimization and Statistical Physics: Low-Rank Matrix Approximation
Nisheeth Vishnoi
11:15am|Simonyi 101 and Remote Access

In this talk, I will present the following two connections between private optimization and statistical physics, both via the problem of approximating a given covariance matrix with a low-rank matrix:

  1. An efficient algorithm to privately compute a low...
