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...

Workshop on Mean Curvature and Regularity

Weyl Law for the phase transition spectrum and density of limit-interfaces
Marco Méndez Guaraco
11:30am|Simonyi Hall 101

Abstract: The Allen-Cahn equation behaves as a desingularization of the area functional. This allows for a PDE approach to the construction of minimal hypersurfaces in closed Riemannian manifolds. After presenting and overview of the subject, I will...

Computer Science/Discrete Mathematics Seminar I

Sunflowers and friends
11:15am|West Building Lecture Hall

The Erdos-Rado sunflower conjecture is one of the tantalizing open problems in combinatorics. In my talk, I will describe several attempts on how to get improved bounds for it. These will lead to surprising connections with several other...

Workshop on Mean Curvature and Regularity

Spacetime aspects of mean curvature in general relativity
10:00am|Simonyi Hall 101

Abstract: This will be an overview of spacetime aspects of mean curvature includingtrapped surfaces, marginally outer trapped surfaces, and the role that they playin the spacetime positive energy theorem and Penrose inequality. We willsurvey the...
