Abstract:

We discuss the prescribed mean curvature flow of a non-compact space-like Cauchy hypersurface of bounded geometry in a generalized Robertson-Walker space-time. The flow preserves the space-likeness condition, and under additional assumptions converges. This extends previous work of Ecker and Huisken
