Description:

Eric A. Autry
Traveling Waves in a Piecewise Linear Reaction-Diffusion Model


We consider the dynamics of a population acting under nonlocal competition for some scarce resource. This can be modeled by an integro-partial differential reaction-diffusion equation. We consider travelling wave solutions describing the migration of the species from a populated region into an uninhabited region. We develop a simplified, analytically tractable, model of this problem, which allows us to then describe the speed and structure of the waves.


Vicky C. Yang
Why do bigger cities have more inventions, crimes, and disease?
A simple mathematical model


As city population doubles, many quantities, such as inventions, robberies, and AIDS cases, more than double. This is called superlinear scaling. We propose a simple mathematical model to explain both why superlinear scaling occurs and why it appears in some quantities more than others.

 

This event is cosponsored by ESAM and SIAM.  Cakes & pastries from Tag's Bakery and coffee from Coffee Lab will be served.
