Members' Colloquium

New Methods in Resolution of Singularities
1:30pm|Simonyi 101 and Remote Access

Since Hironaka's famous resolution of singularities in characteristics zero in 1964, it took about 40 years of intensive work of many mathematicians to simplify the method, describe it using conceptual tools and establish its functoriality. However...

IAS High Energy Theory Seminar

Entanglement Bootstrap and Conformal Field Theory
John McGreevy
2:30pm|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: Entanglement Bootstrap is a research program to understand and extract the universal data of quantum many body states from local entanglement information.  Since this universal data is usually encoded in a quantum field theory, the program...

Joint IAS/PU Arithmetic Geometry

Frobenius Lifting and a Geometric Theory of Companion Forms
Vincent Pilloni
3:30pm|Simonyi 101 and Remote Access

We describe the obstruction to lift Frobenius on certain Shimura varieties and apply this to the theory of companion forms for classical modular forms (Gross, Coleman-Voloch, Faltings-Jordan) and also in higher dimension.

Computer Science/Discrete Mathematics Seminar II

On Turán Numbers of Tight Cycles
10:30am|Simonyi 101 and Remote Access

The study of Turán numbers of graphs and hypergraphs is a rich problem in extremal combinatorics. The Turán problem asks, given a fixed forbidden (hyper)graph F, what is the maximum number of edges in an F-free (hyper)graph in terms of the number of...

Estimates for Ricci Solitons in Dimension 4
2:30pm|Simonyi Hall 101 and Remote Access

Ricci solitons are the self-similar solutions to the Ricci flow, which is the heat equation for Riemannian metrics, and they model singularity formation. We survey various estimates for Ricci solitons in dimension 4. This is mainly the work of...
