Topology Seminar
TIME: 10:10a.m. -11:00a.m.
ROOM: Ayres Hall 015
SPEAKER: Anastasiia Tsvietkova
TITLE: Cat(0) spaces II
DE and Applied/Computational Math Seminar
TIME: 3:35 p.m. - 4:25 p.m.
ROOM: Ayres Hall 309A
SPEAKER: Dr. Grozdena Todorova
TITLE: Damped nonlinear Schrödinger equations
ABSTRACT: Abstract: We consider the Cauchy problem for the damped nonlinear
Schrödinger equations, and prove some blowup and global existence results
dependent on the size of the damping coefficient. We also discuss the L concentration
phenomenon (the so called “strong collapse”) of blowup solutions
in the critical case.

TOPOLOGY SEMINAR
TIME: 10:10a.m. -11:00a.m.
ROOM: Ayres Hall 015
SPEAKER: Conrad Plaut
TITLE: Uniform Universal Covers III
Algebra Seminar
TIME: 3:35 p.m. - 4:25 p.m.
ROOM: Ayres Hall 309B
SPEAKER: Professor Anderson
ABSTRACT: The topic this semester will be an introduction to homological algebra.
This should be of particular interest to students in algebra or topology.
The only prerequisite is some knowledge of module theory (as in Math 552).
The first several meetings will be lectures by Professor Anderson.

Probability Seminar
TIME: 10:10a.m. - 11:00a.m.
ROOM: 309B
SPEAKER: Professor Shui Feng, McMaster University, Canada
TITLE: Poisson-Dirichlet Distribution and Dirichlet Process
Friday February 23, 2007
Colloquium
Time: 3:35p.m.-4:25p.m.
ROOM: Ayres Hall 214
Speaker: Professor John McCarthy, Washington University, St. Louis
Title: What happens when the irresistible force of Functional Analysis meets
the immovable object of Algebraic Geometry?
Abstract: In this talk we shall look at bounded subsets of varieties in $C2$,
such as $\{ (z,w) : z2 = w2(1-w), |z| < 4 \}$, and see what Functional
Analysis can tell us about their geometry. I hope to convince you that there
is not an unbridgeable gap between them. This is joint work with Jim Agler,
and there is a preprint called "Hyperbolic algebraic and analytic curves"
available at http://www.math.wustl.edu/~mccarthy/papers.html.
