Abstract

We consider the quermassintegral preserving flow of closed \emph{h-convex} hypersurfaces in hyperbolic space with the speed given by any positive power of a smooth symmetric, strictly increasing, and homogeneous of degree one function ff of the principal curvatures which is inverse concave and has dual ff_* approaching zero on the boundary of the positive cone. We prove that if the initial hypersurface is \emph{h-convex}, then the solution of the flow becomes strictly \emph{h-convex} for t>0t>0, the flow exists for all time and converges to a geodesic sphere exponentially in the smooth topology.
