- Abstract: We discuss recent progress on a joint project with Pengfei Guan regarding locally constrained flows of hypersurfaces in hyperbolic space and hemispheres. Under explicit initial radial-slope conditions, we establish the long-time existence and exponential convergence of smooth, admissible, star-shaped hypersurfaces to a geodesic sphere. These flows yield new proofs of sharp Alexandrov-Fenchel quermassintegral inequalities in space forms.
