Nonlocal calculus, nonlocal balance laws and asymptotically compatible discretizations
Wednesday, 3/19/2014, 8:00pm - 11:59pm
Speaker: Qiang Du, Penn State University
Abstract: Nonlocality is ubiquitous in nature. While partial differential
equations (PDE) have been used as effective models of many physical
processes, nonlocal models and nonlocal balanced laws are also attracting
more and more attentions as possible alternatives to treat anomalous
process and singular behavior. In this talk, we exploit the use of a
recently developed nonlocal vector calculus to study a class of constrained
value problems on bounded domains associated with some nonlocal

A Case of Anything Goes in Infinite Ergodic Theory
Friday, 3/7/2014, 8:00pm - 11:59pm
Speaker: Terry Adams, US DoD
Authors: Terry Adams and Cesar Silva
Tuesday, 3/4/2014, 9:00pm - 11:59pm
Location: Seminar Room (Monroe Hall 267)
Abstract: In this talk I will give an overview of computability theory. I will discuss the basic concepts and ideas of the field, the types of things we study, and give some fun examples of "computable" and "noncomputable" objects. This talk should be accessible to all math graduate students.

Border-Collision Bifurcations in A Piece-Wise Smooth Planar Dynamical System Associated with Cardiac Potential
Tuesday, 2/25/2014, 8:00pm - 11:59pm
Speaker: Irina Popovici, US Naval Academy
Time:Tuesday, February 25, 3:00 PM
Abstract: The talk addresses the bifurcations of a two-dimensional non-linear dynamical system introduced by Kline and Baker to model cardiac rhythmic response to periodic stimulation. The dynamical behavior of this continuous (but only piece-wise smooth) model transitions from simple (a unique attracting cycle) to complicated (co-existence of stable cycles) as the stimulus period is decreased from large towards zero.
