Mathematical Physics Seminar

An Introduction to Grassmann integrals with applications to statistical mechanics.
Vieri Mastropietro
4:30pm|Simonyi Hall 101 and Remote Access

Grassmann integrals are integrals over functions on an exterior algebra. In the "Gaussian" case they can be expressed as a determinant or Pfaffian.

These integral arise in two dimensional Ising models and random tilings or dimers. 

We review the...

Review of vanishing for bounded cohomology, in preparation for stability
Nicolas Monod
11:00am|Simonyi 101 and Remote Access

This lecture serves as a background for the upcoming talk by Bharatram Rangarajan. I will review some aspects of bounded cohomology, including why it appears to have some relevance to stability questions. I will then explain vanishing results for...

Computer Science/Discrete Mathematics Seminar II

Hardness of Easy Problems and Fine-Grained Complexity
Or Zamir
10:30am|Simonyi Hall 101 and Remote Access

In recent years, a new “fine-grained” theory of computational hardness has been developed, based on “fine-grained reductions” that focus on exact running times for problems. 

We follow the fashion of NP-hardness in a more delicate manner. We...

Members' Colloquium

The orbit method, microlocal analysis and applications to L-functions
Paul Nelson
2:00pm|Simonyi Hall 101 and Remote Access

I will describe how the orbit method can be developed in a quantitative form, along the lines of microlocal analysis, and applied to local problems in representation theory and global problems involving the analysis of automorphic forms. This talk...
