ROOM: HBB 112
SPEAKER: Professor Jerzy Dydak
TITLE: “Topological Interpretations of Property A II”
ABSTRACT: We will present the second interpretation of Property A: large scale paracompact spaces.
ALGEBRA SEMINAR

ANALYSIS SEMINAR
TIME: 3:35 – 4:30 p.m.
ROOM: AC 113
SPEAKER: Asst Prof Remus Nicoara
TITLE: “A finiteness result for lattices of matrix algebras, III"
ABSTRACT: We prove a finiteness result for 2x3 lattices of matrix algebras satisfying a certain "large relative commutant" condition. As a consequence, we obtain finiteness results for the standard invariants of large classes of subfactors.

SPEAKER: Asst Prof Fernando Schwartz
TITLE: "Basics of Optimal Transportation", Topics in Optimal Transportation
Thursday, September 10
JUNIOR COLLOQUIUM
TIME: 3:35 – 4:35 p.m.
ROOM: HBB 102
SPEAKER: Professor Mark Meerschaert, Michigan State University
TITLE: “The Fractal Calculus Project”
ABSTRACT: Fractional derivatives are almost as old as their integer-order cousins. Recently, fractional derivatives have found new applications in engineering, physics, finance, and hydrology. In physics, fractional derivatives are used to model anomalous diffusion, where a cloud of particles spreads ...expanded abstract
The entire talk will be accessible to advanced undergraduate students.

TOPOLOGY SEMINAR
TIME: 11:15 – 12:05 p.m., Friday, September 11, 2009
ROOM: JHB 12
SPEAKER: Mr.Jared Bunn
TITLE: “Introduction to Jones polynomial”
ABSTRACT: Jones polynomial (From Wikipedia, the free encyclopedia) In the mathematical field of knot theory, the Jones polynomial is a knot polynomial discovered by Vaughan Jones in 1983. Specifically, it is an invariant of an oriented knot or link which assigns to each oriented knot or link a Laurent polyomial in the variable t1 / 2 with integer coefficients.

COLLOQUIUM
TIME: 3:35 – 4:35 p.m.
ROOM: HBB 102
SPEAKER: Professor Mark Meerschaert, Michigan State University
TITLE: “Tempered Stable Models for Anomalous Diffusion”
ABSTRACT: The fractional diffusion equation replaces the usual first order time derivative, and second order spatial derivative, by their fractional order analogues. Stable processes with non-Markovian inverse stable subordinators are governed by the fractional diffusion equation, in the same way that Brownian motion is governed by the classical diffusion equation. In certain applications to hydrology and finance, plume evolution is intermediate between the classical and fractional case. For example, daily price returns are heavy tailed, but annual returns are essentially Gaussian. Then a subordinated process involving tempered stable laws is effective at capturing the real world dynamics. The governing equation involves tapered fractional derivatives. Applications to ground water pollution migration illustrate the practical utility of the results.
