# Seminars & Events for 2007-2008

May 1, 2008
4:30pm - 6:30pm
##### HF-hat for 3-manifolds with boundary, via a toy example
###### Topology Seminar

We will start by sketching the nature of our extension of HF-hat to 3-manifolds with boundary. Following this, we will focus on a toy model, in terms of planar grid diagrams, in which the main aspects of the theory can be readily seen. We will conclude by mentioning the additional complications not present in the toy model.

This is joint work with P. Ozsvath and D. Thurston.

##### Multizeta values and related structures in function field arithmetic
###### Princeton University/IAS Number Theory Seminar
Speaker: D. Thakur, IAS
Location:
IAS - Simonyi Hall Seminar Room SH-101
May 5, 2008
4:30pm - 6:30pm
##### Game Options, Risk and their Binomial Approximations
###### Operations Research and Financial Engineering

Game (Israeli) options which I introduced in 2000 extend the setup of American options by allowing their issuer to call them back (cancell) paying certain penalty for that. Pricing of such options leads to Dynkin’s optimal stopping games.

May 6, 2008
4:30pm - 6:30pm
##### From an analogue of Ewens' measure on the unitary group to the circular Jacobi ensemble
###### Operations Research and Financial Engineering
Speaker: Ashkan Nikeghbali, Eidgenössische Technische Hochschule Zürich (ETH)
Location:
May 7, 2008
2:00pm - 4:00pm
##### Nonconvergence examples in averaging
###### Ergodic Theory & Statistical Mechanics

Systems which combine fast and slow motions lead to complicated two scale equations and the averaging principle suggests to approximate the slow motion by averaging in fast variables.

4:30pm - 6:30pm
##### The Divisor Matrix, Dirichlet Series and SL(2,Z)
###### Princeton University/IAS Number Theory Seminar

The divisor matrix is indexed by the natural numbers with $(i,j)$ entry equal to $1$ if $i$ divides $j$ and $0$ otherwise. The convolution of a Dirichlet series with the Riemann zeta function corresponds to multiplication of the sequence of coefficients by the divisor matrix.
