Correlations of Characteristic Polynomials of Wigner Matrices
Holger Koesters
(Bielefeld)
Abstract:
The characteristic polynomials of random matrices from various random matrix ensembles have been investigated over the last few years. In this talk I will present some results
on the correlations of the characteristic polynomials of general Wigner matrices. It turns out that the well-known results for Gaussian Wigner matrices essentially continue to hold in this setting. This talk is partly based on joint work
with Friedrich Goetze.

Generalizing topological A- and B-models
📍 London
Vid Stojevic
(Hamburg)
Abstract:
I will talk about my recent work (0801.1160, 0809.4034) on
generalizing the A- and B-models via the Alexandrov-Kontsevich-Schwarz-Zaboronsky (AKSZ) construction, in the context of both flux compactifications, and the doubled geometry of Hull.

Quantum Strings in AdS4 x P3
Tristan McLoughlin
(Max Planck Institute)
Abstract:
There has been much recent interest in the proposed
duality between superstrings in the curved geometry AdS_4 x P3 and
three dimensional N=6 supersymmetric Chern-Simons theory –
a new, concrete, example of the holographic AdS/CFT correspondence.
This dual pair has additionally been conjectured to
be an integrable system in the planar limit.
In this talk I will discuss several classes of classical
strings moving in this background, and their quantum corrections,
as tools to probe the duality and to test the conjectured integrable
structure.

Deformations: from analysis to algera and back
Raphael Rouquier
(Oxford University)
Abstract:
We will introduce deformations of partial derivatives (Dunkl
operators) and discuss their actions on polynomial functions. This leads to various flavours of Hecke algebras and relates to the geometry of families of points in the plane. Eventually, this can be studied through microlocal analysis.
