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.

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.
