Description
Traveling waves in reaction-diffusion equations have been very useful in
modeling various propagation phenomena in physics, biology and other
sciences. Recently there has been a lot of mathematical works on the
possible effect of a fluid flow or wind on front propagation, when the
flow is prescribed. Such a flow may significantly enhance the front speed
as well as extinguish a flame depending on the geometry of the flow, its
amplitude, and the relation of the flow scales to those of the reaction
front. We will review our results that exhibit and quantify these
phenomena in shear, cellular and other flows. We will also discuss our
recent results in the analysis of the reactive Boussinesq system when the
flow is generated by the temperature differences.
3:45 Refreshments will be served before the talk in 551 Kerr Hall
