The perpendicular Neumann problem for mean curvature flow with a timelike cone boundary condition. (English) Zbl 1296.53131
Summary: This paper demonstrates existence for all time of mean curvature flow in Minkowski space with a perpendicular Neumann boundary condition, where the boundary manifold is a convex cone and the flowing manifold is initially space-like. Using a blowdown argument, we show that under renormalisation this flow converges towards a homothetically expanding hyperbolic solution.
