Symplectic Dynamics Working Group

Hamiltonian pseudo-rotations of projective spaces.
1:30pm|Simonyi Hall Classroom 114

I will talk about Ginzburg and Gurel's work on Hamiltonian pseudo-rotations of projective spaces, in particular, their proof of no fixed point of a pseudo-rotation of projective space is isolated as an invariant set.

Workshop on Mean Curvature and Regularity

Topological uniqueness of self-expanders of small entropy
11:30am|Simonyi Hall 101

Abstract: In this talk we show that given any regular cone with entropy less than that of round cylinder, all smooth self-expanding solutions of the mean curvature flow that are asymptotic to the cone are in the same isotopy class. This is joint...

Workshop on Mean Curvature and Regularity

Boundary regularity for area minimizing currents and a question of Almgren
10:00am|Simonyi Hall 101

Abstract: Consider an area minimizing integral current $T$ which has a smooth boundary $\Gamma$ of multiplicity $1$ in some smooth Riemannian ambient manifold $\Sigma$. If the current has codimension $1$ a famous work of Hardt and Simon gives full...

Workshop on Mean Curvature and Regularity

Some minimal submanifolds generalizing the Clifford torus
Jaigyoung Choe
2:30pm|Simonyi Hall 101

Abstract: The Clifford torus is the simplest nontotally geodesic minimal surface in S^3. It is a product surface, it is helicoidal, and it is a solution obtained by separation of variables. We will show that there are more minimal submanifolds with...

Theoretical Machine Learning Seminar

Scalable natural gradient training of neural networks
12:15pm|Princeton University, CS 302

Natural gradient descent holds the potential to speed up training of neural networks by correcting for the problem geometry and achieving desirable invariance properties. I’ll present Kronecker-Factored Approximate Curvature (K-FAC), a scalable...
