Joint IAS/Princeton University Number Theory Seminar

Singular moduli for real quadratic fields
4:30pm|Simonyi Hall 101

The theory of complex multiplication describes finite abelian extensions of imaginary quadratic number fields using singular moduli, which are special values of modular functions at CM points. I will describe joint work with Henri Darmon in the...

Working Seminar on Algebraic Number Theory

p-adic L-functions in one and two variables
Kim Tuan Do
2:15pm|Simonyi Hall 101

Introduce the L-function, and then the p-adic L-function, of a cusp form, and the of a Hida family of cups forms. What we need is in Fukaya-Kato Sections 4.4-4.5. See also: Mazur-Tate-Teitelbaum and Mazur's "Anomalous eigenforms" note.

Analysis Seminar

Higher Regularity of the Singular Set in the Thin Obstacle Problem.
1:00pm|Simonyi Hall 101

In this talk, I will give an overview of some of what is known about solutions to the thin obstacle problem, and then move on to a discussion of a higher regularity result on the singular part of the free boundary. This is joint work with Xavier...

Mathematical Conversations

A glamorous movie star, the "bad boy" of music, and the development of spread spectrum communications
6:00pm|Dilworth Room

An unlikely couple devised one of the first spread spectrum communication systems. Today these systems use sophisticated mathematics and are ubiquitous. This is a verbatim repeat (by popular demand) of a talk I gave about 6 years ago.

Variational Methods in Geometry Seminar

Constrained deformations of positive scalar curvature metrics
3:30pm|Simonyi Hall 101

I will present a series of results concerning the interplay between two different curvature conditions, in the special case when these are given by pointwise inequalities on the scalar curvature of a manifold, and the mean curvature of its boundary...

Variational Methods in Geometry Seminar

Stable hypersurfaces with prescribed mean curvature
1:00pm|Simonyi Hall 101

In recent works with N. Wickramasekera we develop a regularity and compactness theory for stable hypersurfaces (technically, integral varifolds) whose generalized mean curvature is prescribed by a (smooth enough) function on the ambient Riemannian...

Computer Science/Discrete Mathematics Seminar II

A high-dimensional Littlewood--Offord inequality
Li-Yang Tan
10:30am|Simonyi Hall 101

We prove a new Littlewood--Offord-type anticoncentration inequality for m-facet polytopes, a high-dimensional generalization of the classic Littlewood--Offord theorem. Joint work with Ryan O'Donnell and Rocco Servedio.
