WebMar 26, 2016 · The mean curvature flow in manifolds with symmetries has been studied by several authors, for example Pacini in [14] considered the evolution of the orbits of a group of isometries. The proof of Theorem 1.1 is based on the fundamental equations for submersions which are derived in the classical paper by O’Neill [13]. WebThe mean curvature flow (MCF) deforms a hypersurface in the normal direction with a speed proportional to its mean curvature. An example of a constrained MCF is the evolution of a closed planar curve enclosing an unique object. This code evolves a curve drawn around a single object picture, the evolution stops at the points which reach the object.
