Joint IAS/Princeton University Algebraic Geometry Seminar

An example of liftings with different Hodge numbers
Shizhang Li
5:00pm|Princeton University, Fine Hall 314

Does a smooth proper variety in positive characteristic know the Hodge number of its liftings? The answer is "of course not". However, it's not that easy to come up with a counter-example. In this talk, I will first introduce the background of this...

Theoretical Machine Learning Seminar

Curiosity, Intrinsic Motivation, and Provably Efficient Maximum Entropy Exploration
Karan Singh
12:15pm|Princeton University, CS 302

Suppose an agent is in an unknown Markov environment in the absence of a reward signal, what might we hope that an agent can efficiently learn to do? One natural, intrinsically defined, objective problem is for the agent to learn a policy which...

An Application of a Conjecture of Mazur-Tate to Supersingular Elliptic Curves
Emmanuel Lecouturier and Emmanuel Lecouturier
4:30pm|Simonyi Hall 101

In 1987, Barry Mazur and John Tate formulated refined conjectures of the "Birch and Swinnerton-Dyer type", and one of these conjectures was essentially proved in the prime conductor case by Ehud de Shalit in 1995. One of the main objects in de...

Analysis Seminar

Elliptic measures and the geometry of domains
1:00pm|Simonyi Hall 101

Given a bounded domain $\Omega$, the harmonic measure $\omega$ is a probability measure on $\partial \Omega$ and it characterizes where a Brownian traveller moving in $\Omega$ is likely to exit the domain from. The elliptic measure is a non...

Mathematical Conversations

Harmonic measure and boundary regularity
6:00pm|Dilworth Room

Given a domain, the harmonic measure is a measure that relates any boundary function to its harmonic extension; it is also the hitting probability of the boundary for a Brownian motion moving inside the domain. We will talk about the relationship...
