ALGEBRA SEMINAR
TIME: 2:30 – 3:20
ROOM: Ayres Hall B004
SPEAKER: Ms. Ashley Rand
TITLE: The talk will continue on K_0(R).

DE/APPLIED and COMPUTATIONAL MATH SEMINAR
TIME: 3:35 – 4:30 p.m.
ROOM: Ayres 113
SPEAKER: Prof. Tuoc Phan
TITLE: "On global time existence of solutions to systems of cross-diffusion equations"

PROBABILITY SEMINAR
TIME: 3:35 – 4:25 p.m.
ROOM: Ayres 122
SPEAKER: Prof. Xia Chen
TITLE: "Existence of intersection local times of the stochastic processes with stationary increments"

Wednesday, November 2, 2011

ANALYSIS-TOPOLOGY SEMINAR
TIME: 2:30 – 3:20 p.m.
ROOM: Ayres 114
SPEAKER: Prof. Jerzy Dydak
TITLE: "Box space of a group and Haagerup property II"
ABSTRACT: I will show that if the box space of a residually finite group G is coarsely embeddable in a Hilbert space, then G has the Haagerup property (it has a proper function of negative type). As a consequence one gets that the box space of the free group F_n, n large enough to allow F_n to be mapped epimorphically onto SL(3,Z), cannot be coarsely embedded into a Hilbert space.

ANALYSIS SEMINAR
TIME: 3:35 – 4:25
ROOM: Ayres 113
SPEAKER: Prof. Remus Nicoara
TITLE: "Subfactors from Commuting Squares"
ABSTRACT: We present some recent results on subfactors constructed from commuting squares.

Thursday, November 3, 2011

MATH BIOLOGY SEMINAR
TIME: 12:45 – 1:35 p.m.
ROOM: NIMBioS Classroom
SPEAKER: Adam Sullivan
ABSTRACT: "Population Dynamics in Temporal and Spatial Domains"

Friday, November 4, 2011

COLLOQUIUM
TIME: 3:35 – 4:25 pm
ROOM: Ayres 405
SPEAKER: Dr. Shuwang Li of Illinois Institute of Technology
TITLE: "Modeling and computation of moving boundary problems"
ABSTRACT: In this talk, I will present two moving boundary problems. The first one is the classical Hele-Shaw problem. Motivated by the linear stability analysis, I introduce the idea of self-similar growth, and then use computational tools to investigate the existence and stability of self-similar solutions in the nonlinear regime. The second problem is about the modeling of a multicomponent membrane in a viscous flow. I will demonstrate how to incorporate the phase decomposition process into this problem, and show some nontrivial effects of the phase domains on the membrane morphology.

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