Symplectic Dynamics/Geometry Seminar

A simplicial construction of G-equivariant Floer homology
Kristen Hendricks
3:30pm|Princeton University, Fine Hall 224

For G a Lie group acting on a symplectic manifold and preserving a pair of Lagrangians, we use techniques from infinity category theory to construct a G-equivariant Floer homology of L0 and L1 without equivariant transversality. We give a sample...

Members’ Seminar

On measures invariant under the diagonal group --- a new approach
2:00pm|Simonyi Hall 101

A key challenge in homogeneous dynamics is understanding the action of higher rank diagonal groups on homogenous spaces. While actions of rank one diagonal groups have a lot of flexibility, a phenomena used already by Artin to engineer orbits of...

Computer Science/Discrete Mathematics Seminar I

2-universality of random graphs.
Gal Kronenberg
11:15am|Simonyi Hall 101

For a family of graphs F, a graph G is F-universal if G contains every graph in F as a (not necessarily induced) subgraph. A natural candidate to serve as universal graph G is the random graph G(n,p). In this case, we want to find an optimal p for...

Hermann Weyl Lectures

The Zilber-Pink conjecture
2:00pm|Simonyi Hall 101

The Zilber-Pink conjecture is a far reaching finiteness conjecture in diophantine geometry, unifying and extending Mordell-Lang and Andre-Oort. This lecture will state the conjecture, illustrate its varied faces, and indicate how the point-counting...

Joint IAS/Princeton University Number Theory Seminar

Irreducible components of affine Deligne-Lusztig varieties and orbital integrals
4:30pm|Simonyi Hall 101

Affine Deligne-Lusztig varieties (ADLV) naturally arise in the study of Shimura varieties and Rapoport-Zink spaces; their irreducible components give rise to interesting algebraic cycles on the special fiber of Shimura varieties. We prove a...

What is a central limit theorem for random groups?
Melanie Wood
6:00pm|Dilworth Room

We will recall the central limit theorem for random numbers, and then discuss the general principle of universality and what it might mean specifically in an analog of the central limit theorem for random groups.
