Geodesics and Laplace spectrum on 3D contact sub-Riemannian manifolds: the Reeb flow
Yves Colin de Verdière
4:30pm|Remote Access

Joint work with Luc Hillairet (Orléans) and Emmanuel Trélat (Paris). A 3D closed manifold with a contact distribution and a metric on it carries a canonical contact form. The associated Reeb flow plays a central role for the asymptotics of the...

Degenerations of Kahler forms on K3 surfaces, and some dynamics
9:15am|Remote Access

K3 surfaces have a rich geometry and admit interesting holomorphic automorphisms. As examples of Calabi-Yau manifolds, they admit Ricci-flat Kähler metrics, and a lot of attention has been devoted to how these metrics degenerate as the Kähler class...

Representation Theory & Categorification
12:15pm|Virtual

In modern representation theory we often study the category of modules over an algebra, in particular its intrinsic and combinatorial structures. Vice versa one can ask the question: which categories have a given combinatorics? This is the basic...

Representation Theory & Combinatorics of the Symmetric Group and Related Structures
Monica Vazirani
11:00am|Virtual

With an eye toward coordinating with the advanced course, we will start with the representation theory of the symmetric group and related combinatorics. We will focus on the functors of induction and restriction. We will then consider related...

Oğuz Şavk (Boğaziçi University), Classical and new plumbings bounding contractible manifolds and homology balls

A central problem in low-dimensional topology asks which homology 3-spheres bound contractible 4-manifolds and homology 4-balls. In this...

Character estimates for classical finite simple groups
4:30pm|Simonyi Hall 101 and Remote Access

This is intended to complement the recent talk of Pham Huu Tiep in this seminar but will not assume familiarity with that talk. The estimates in the title are upper bounds of the form $|\chi(g)| \le \chi(1)^\alpha$, where $\chi$ is irreducible and $...
