Abstract

We consider a reaction-diffusion-advection system which is a model for chemotaxis with growth. An appropriate singular limit of this system yields a free-boundary problem where the interface motion depends on the mean curvature and on some nonlocal term. We prove local-in-time existence, uniqueness and regularity for this free-boundary problem and investigate some qualitative properties (lack of monotonicity, loss of convexity). We then establish the convergence of the solution of the reaction-diffusion-advection system to the solution of the free-boundary problem.
