March 26, Zhiren Wang (Yale Univ.) Title: Global
rigidity of abelian Anosov
actions

Abstract: As
part of a more general conjecture by Katok and Spatzier,

it was asked if all smooth Anosov $Z^r$-actions on tori, nilmanifolds

and infranilmanifolds
without rank-1 factor actions are, up to smooth conjugacy,

actions by automorphisms.
In this talk, we will discuss a recent joint work with

Federico Rodriguez Hertz that affirmatively answers this question.

April
2, Gangotryi Sorcar (SUNY at Binghamton), Title: Teichmuller space of negatively curved
manifolds

Abstract: In
this talk I will give an overview of existing results on

the non-contractibility of the Teichmuller
space of hyperbolic manifolds

and also talk about some similar new findings
on Gromov-Thurston

manifolds $M$ that
are not hyperbolic but negatively curved.

I will outline the construction of a non-trivial element in

$\pi_{**1}** ({\mathcal
T}^{\infty} (M))$, where ${\mathcal
T}^{\infty}(M)$

denotes the Teichmuller
space of all negatively curved Riemannian

metrics on $M$, which is the quotient space of the space of
all negatively

curved Riemannian metrics on $M$ modulo the
space of all isotopies of $M$

that
are homotopic to the identity. Time permitting, I
will also talk about the

higher homotopy
groups of ${\mathcal
T}^{\infty}(M)$.

April
9, QuanLie Fan, Title: On some
problems in multivariable operator theory.

Abstract:
Multivariable operator theory, the study of several operators

or an algebra of operators at a time, started
more recently compared to

classical single variable operator theory on
Hilbert spaces.

In this talk we will give an introduction of multivariable operator
theory.

We will
discuss problems on some reproducing Kernel Hilbert spaces

and the interplay between harmonic analysis and
operator theory.

April 23, Alexander Kheyfits,
Distribution of zeros of entire and analytic functions.

curves
