Asymptotic front speeds in random flows
PDE & Applied Mathematics| Speaker: | Jack Xin, University of California at Irvine |

Description
An overview will be given on reaction-diffusion fronts in
random flows and related homogenization of stochastic Hamilton-Jacobi
equations. Variational formulas of front speeds of
Kolmogorov-Petrovsky-Piskunov fronts will be derived from large deviation
properties of the random flows. Asymptotics and computations of front
speeds based on variational principles will be shown for various
compressible and incompressible random flows.
