Regularity of Hele-Shaw Flow with source and drift

Inwon Kim, Yuming Paul Zhang

In this paper we study the regularity property of Hele-Shaw flow, where source and drift are present in the evolution. More specifically we consider Hölder continuous source and Li…

Homogenization for Space-Time-Dependent KPP Reaction-Diffusion Equations and G-Equations

Yuming Paul Zhang, Andrej Zlatos

We prove stochastic homogenization for reaction-advection-diffusion equations with random space-time-dependent KPP reactions with temporal correlations that are decaying in an appr…
