主講內(nèi)容:
In this talk, we study fully nonlinear curvature flows of noncompact spacelike hypersurfaces in Minkowski space. We prove that if the initial hypersurface is strictly convex and satisfies certain conditions, then the flow exists for all time. Moreover, we show that after rescaling the flow converges to a self-expander. We also will study the existence of self-expander with prescribed asymptotic behavior.
