| Title | Random Matrix Theory: Applications and Universality Questions |
|---|
| Abstract |
Random Matrix Theory (RMT) is currently of considerable interest
in physics as well as in mathematics.
An important aspect of RMT is that its results are believed
to be applicable to a wide variety of physical,
mathematical and applied mathematical situations (universal).
Applications of RMT include:
- statistical properties of many-body quantum systems
- statistics of eigenvalues of classically chaotic quantum systems
- elastomechanic resonances
- random particle systems with particular focus on percolation
problems
- random growth models
- transport problems
- number theory (distribution of zeros of the Riemann
zeta-function)
- combinatorial problems (longest increasing subsequences,
hard-drive disk scheduling problem).
A central mathematical issue in RMT which arose very early
is universality within random matrix models themselves,
and this is currently my main research focus.
The talk will start with an intoduction to RMT and its
applications.
After that I will describe our recent work
with Percy Deift (Courant Institute)
on the proof of the Universality Conjecture in RMT for orthogonal and
symplectic ensembles.
Finally, several open problems and ongoing projects
will be described.

| Title | Inverse Problem for Gibbs Fields |
|---|
| Abstract | Given a potential of pair interaction and a value of
activity, one can construct the corresponding Gibbs distribution in a
finite domain L Ì Zd. It is well known that
for small values of activity there exist the infinite volume (
L® Zd) limiting Gibbs distribution and the
infinite volume correlation functions. We prove the converse of this
classical result - we show that given r1 and r2(x), where
r1 is a constant and r2(x) is a function on
Zd, which are sufficiently small, there exist a pair
potential and a value of activity, for which r1 is the density
and r2(x) is the pair correlation function

| Title | Moment asymptotics associated with large permutation groups |
|---|
| Abstract | In estimating the tail probability, the moment estimation is one of the efective approaches, especially when the logarithmic generating function is hard to compute. This is often the case as we study the upper tail behaviors of the intersection local times or, the local times of the multi-parameter processes. In these situations, the moment can usually be written in the form of permutation sums. In this talk we discuss two examples, in which the moment asymptotics will be established and some new approaches of applying these moment asymptotics will be introduced. |

| Title | ON THE ROBIN PROBLEM IN FRACTAL DOMAINS |
|---|
| Abstract | The "Robin problem" or the "third boundary
problem" is a mathematical
model for the flow of a substance (or heat)
out of a domain through a semipermeable
membrane. I will address the question
of when the concentration
of the substance (or the temperature)
is bounded below by a constant over the
whole domain. The problem is analytic,
the techniques used in proofs are largely
probabilistic.
Joint work with Rich Bass and Zhenqing Chen.
