Monday, March 5

ALGEBRA SEMINAR
TIME: 2:30 - 3:20 p.m.
ROOM: Ayres B004
SPEAKER: Mr. Jesse Smith
TITLE: Zero-dimensional Rings
ABSTRACT: We will discuss several properties of zero-dimensional commutative rings. In particular, we will discuss commutative von Neumann regular rings and when the product of zero-dimensional rings is zero-dimensional.

MATH BIOLOGY SEMINAR
TIME: 2:30 - 3:20 p.m.
ROOM: Ayres 121
SPEAKER: Cristina Lanzas
TOPIC: More on parameter estimation and sensitivity

PROBABILITY SEMINAR
TIME: 3:35 – 4:25 p.m.
ROOM: Ayres 122
SPEAKER: Prof. Vasileios Maroulas
TITLE: Small noise large deviations and applications II
ABSTRACT: A different approach for establishing large deviations and two examples were presented in the first part of the lecture. An example how large deviations for stochastic flows of diffeomorphisms attack to an image analysis problem will be continued. We will get exposed to large deviations for an optimal filtering problem where the observation process is corrupted by fractional Brownian noise. Large deviations for a math finance stochastic model will be briefly discussed as well. The talk is based on joint works with A. Budhiraja, P. Dupuis, J. Xiong, J. Huang, and X. Li.

Wednesday, March 7

TOPOLOGY SEMINAR
TIME: 2:30 - 3:20 p.m.
ROOM: Ayres G004
SPEAKER: Prof. Jim Conant
TITLE: An introduction to the Novikov conjecture - 4
ABSTRACT: I will attempt to introduce all of the necessary topological ingredients to understand Novikov's conjecture in the way it was originally presented by him in a 1970 paper. I will be following the book by Matthias Kreck and Wolfgang Lück.

ANALYSIS SEMINAR
TIME: 3:35 - 4:25 p.m.
ROOM: Ayres 112
SPEAKER: Prof. Remus Nicoara
TITLE: Cartan Subalgebras of von Neumann Algebras
ABSTRACT: A Cartan subalgebra A of M is a maximal abelian subalgebra which together with its normalizer generates M. Existence and uniqueness results for Cartan subalgebras turn out to be major tools in the classification of von Neumann algebras. We will present a survey of some of the known results so far - due to Connes, Jones, Popa, Vaes, Ioana.

Friday, March 9

COLLOQUIUM
TIME: 3:35 – 4:25 pm
ROOM: Ayres 405
SPEAKER: Dr. Atanas Stefanov, University of Kansas
TITLE: Stability of solitary wave solutions for dispersive PDE's
ABSTRACT: In the modern PDE theory, special attention is paid to solutions with special properties, which are observed in experiments and real physical situations. There are various types of these, so called solitons or coherent structures - pulses, fronts, backs, which may be traveling or standing waves etc., each one arising in different models and of great practical significance. Of particular interest will be the stability (both linear and nonlinear) of such objects. In this talk, I will present the current state of affairs as well as some new results about the linear stability of traveling and standing waves of certain second order in time models.

Refreshments will be available in Ayres 401 at 3:15 p.m.
