Title: Entire $sigma_k$ curvature flow in Minkowski space
Abstract: In this talk, we will discuss the $sigma_k$ curvature flow of noncompact spacelike hypersurfaces in Minkowski space. We show that if the initial hypersurface satisfies certain conditions, then the flow exists for all time. Moreover, we show that after rescaling, the flow converges to a self-expander. This is a joint work with Zhizhang Wang.
