Computer Science/Discrete Mathematics Seminar I

Thresholds Versus Fractional Expectation-Thresholds
Keith Frankston
11:00am|Simonyi Hall 101

Given an increasing family F in {0,1}^n, its measure according to mu_p increases and often exhibits a threshold behavior, growing quickly as p increases from near 0 to near 1 around a specific value p_c. Thresholds of families have been of great...

Analysis/Mathematical Physics Seminar

A rigorous derivation of the kinetic wave equation
Tristan Buckmaster
5:15pm|Simonyi Hall 101

In this talk I will outline recent work in collaboration with Pierre Germain, Zaher Hani and Jalal Shatah regarding a rigorous derivation of the kinetic wave equation. The proof presented will rely of methods from PDE, statistical physics and number...

Analysis/Mathematical Physics Seminar

Localization and unique continuation on the integer lattice
Charles Smart
4:00pm|Simonyi Hall 101

I will discuss recent results on localization for the Anderson--Bernoulli model. This will include my work with Ding as well as work by Li--Zhang. Both develop new unique continuation results for the Laplacian on the integer lattice.

Joint IAS/Princeton University Number Theory Seminar

The arithmetic fundamental lemma for unitary groups: an update
4:30pm|Princeton University, Fine 214

This is an update on the talk I gave about 10 years ago on this seminar. The arithmetic Gan-Gross-Prasad (AGGP) conjecture, a high dimensional generalization of the Gross–Zagier theorem, relates the height pairing of arithmetic diagonal cycles on...

Mathematical Conversations

Cohomology Theories and Formal Groups
6:00pm|Dilworth Room

In the 1960's, Quillen found a remarkable relationship between a certain class of cohomology theories and the theory of formal groups. This discovery has had a profound impact on the development of stable homotopy theory. In this talk, I'll give a...

Computer Science/Discrete Mathematics Seminar II

Graph removal lemmas
10:30am|Simonyi Hall 101

Continuing last week's lecture, among the numerous applications of the regularity lemma, a classical one is the graph removal lemma. It has applications in fields such as number theory and theoretical computer science. For every fixed graph H, the H...

Analysis Seminar

On the gradient-flow structure of multiphase mean curvature flow
Tim Laux
5:00pm|Simonyi Hall 101

Due to its importance in materials science where it models the slow relaxation of grain boundaries, multiphase mean curvature flow has received a lot of attention over the last decades.

In this talk, I want to present two theorems. The first one is...

Symplectic Dynamics/Geometry Seminar

Convex hypersurface theory in higher-dimensional contact topology
Ko Honda
3:30pm|Princeton University, Fine Hall 224

Convex surface theory and bypasses are extremely powerful tools for analyzing contact 3-manifolds. In particular they have been successfully applied to many classification problems. After briefly reviewing convex surface theory in dimension three...
