In such a warped product manifold, we can define the notion of a graph, called a geodesic graph. We prove that the curve shortening flow preserves a geodesic graph for any warping function, and the mean curvature flow of hypersurfaces preserves a geodesic graph for some monotone convex warping functions. In particular, we consider some warping functions that go to zero at infinity, which means that the curves or hypersurfaces go to a point at infinity along the flow. In such a case, we prove the long-time existence of the flow and that the curvature and its higher-order derivatives go to zero along the flow.", "revisions": [ { "version": "v1", "updated": "2023-09-28T13:59:09.000Z" } ], "analyses": { "subjects": [ "53C44" ], "keywords": [ "warped product manifold", "geodesic graph", "graphs sliding", "study mean curvature flows", "curve shortening flow preserves" ], "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable" } } }
