Special Groups and Dynamics Seminar - Part 2

Spectral Gap of the Laplacian for Random Hyperbolic Surfaces
Nalini Anantharaman
2:30pm|Rubenstein Commons | Meeting Room 5

Although there are several ways to ''choose a compact hyperbolic surface at random'', putting the Weil-Petersson probability measure on the moduli space of hyperbolic surfaces of a given topology is certainly the most natural. The work of M...

Special Year Seminar I

Toric Vector Bundles
2:00pm|Simonyi 101

This will be an expository talk on the structure and classification of equivariant vector bundles on toric varieties. I will emphasize Klyachko's classification results from the 1980s and 1990s and discuss more recent re-formulations of this...

Special Year on Algebraic and Geometric Combinatorics

12:00am

During the 2024-25 academic year the School will have a special program on Algebraic and Geometric Combinatorics. June Huh from Princeton University will be the Distinguished Visiting Professor.

Mathematical objects often have a combinatorial...

Symplectic Orbifold Gromov-Witten Invariants.
Mark McLean
9:15am|Remote Access

Chen and Ruan constructed symplectic orbifold Gromov-Witten invariants more than 20 years ago.  In ongoing work with Alex Ritter, we show that moduli spaces of pseudo-holomorphic curves mapping to a symplectic orbifold admit global Kuranishi charts...

Inertial Manifolds for the Hyperbolic Cahn-Hilliard Equation
Ahmed Bonfoh
2:30pm|Simonyi Hall 101 and Remote Access

An inertial manifold is a positively invariant smooth finite-dimensional manifold which contains the global attractor and which attracts the trajectories at a uniform exponential rate. It follows that the infinite-dimensional dynamical system is...

Two or infinity
Dan Cristofaro-Gardiner
9:15am|Remote Access

It is conjectured that every Reeb flow on a closed three-manifold has either two, or infinitely many, simple periodic orbits. I will survey what is currently known about this conjecture. Then, I will try to explain some of the key ideas behind...

Visions in Arithmetic and Beyond: Celebrating Peter Sarnak's Work and Impact

Higher Order Fourier Uniformity of Bounded Multiplicative Functions in Short Intervals
Terence Tao
4:30pm|Princeton University McDonnell A02

Abstract: The Higher order Fourier uniformity conjecture asserts that on most short intervals, the Mobius function is asymptotically uniform in the sense of Gowers; in particular, its normalized Fourier coefficients decay to zero.  This conjecture...

Visions in Arithmetic and Beyond: Celebrating Peter Sarnak's Work and Impact

Random Lattices with Symmetries
Maryna Viazovska
2:30pm|Princeton University McDonnell A02

Abstract: What is the densest lattice sphere packing in the d-dimensional Euclidean space? In this talk we will investigate this question as dimension d goes to infinity and we will focus on the lower bounds for the best packing density, or in other...
