摘要:

In this paper, we consider the surface area preserving mean curvature flow in quasi-Fuchsian 3-manifolds. We show that the flow exists for all times and converges exponentially to a smooth surface of constant mean curvature with the same surface area as the initial surface.

关键词: quasi-Fuchsian 3-manifold, parabolic equation, maximum principle
