Variational Methods in Geometry Seminar

Translators for Mean Curvature Flow
David Hoffman
1:00pm|Simonyi Hall 101

A translator for mean curvature flow is a hypersurface $M$ with the property that translation is a mean curvature flow. That is, if the translation is $t\rightarrow M+t\vec{v}$, then the normal component of the velocity vector $\vec{v}$ is equal to...

Symplectic Dynamics/Geometry Seminar

Distinguishing fillings via dynamics of Fukaya categories
Yusuf Barış Kartal
3:30pm|Simonyi Hall 101

Given a Weinstein domain $M$ and a compactly supported, exact symplectomorphism $\phi$, one can construct the open symplectic mapping torus $T_\phi$. Its contact boundary is independent of $\phi$ and thus $T_\phi$ gives a Weinstein filling of $T_0...

Members’ Seminar

Invertible objects in stable homotopy theory
2:00pm|Simonyi Hall 101

Computation of the stable homotopy groups of spheres is a long-standing open problem in algebraic topology. I will describe how chromatic homotopy theory uses localization of categories, analogous to localization for rings and modules, to split this...

Theoretical Machine Learning Seminar

Generalized Framework for Nonlinear Acceleration
Damien Scieur
12:15pm|White Levy Room

Nonlinear Acceleration Algorithms, such as BFGS, were widely used in optimization due to their impressive performance even for large scale problems. However, these methods present a non negligeable number of drawbacks, such as a strong lack of...

Workshop on Mean Curvature and Regularity

Progress in the theory of CMC surfaces in locally homgeneous 3-manifolds X
William Meeks
11:30am|Simonyi Hall 101

Abstract: I will go over some recent work that I have been involved in on surface geometry in complete locally homogeneous 3-manifolds X. In joint work with Mira, Perez and Ros, we have been able to finish a long term project related to the Hopf...

Workshop on Mean Curvature and Regularity

Free boundary minimal Möbius bands
10:00am|Simonyi Hall 101

Abstract: We will discuss a new family of free boundary minimal Möbius bands in $B^4$ that are critical for higher Steklov eigenvalues among $S^1$-invariant metrics.

Joint IAS/Princeton University Number Theory Seminar

Epsilon dichotomy for linear models
4:30pm|Princeton University, Fine Hall 214

Saito--Tunnell theorem is a local version of Waldspurger's formula, relating the existence of E^\times invariant linear forms on representation of GL_2 to local root numbers. I present a generalization of this which relates the existence of GL_n(E)...
