| contents | The aim of this paper is to generalize the work of B. Buet and M. Rumpf on some definition of the approximate mean curvature vector for varifolds, and its associated mean curvature motions for points clouds. We propose a generalization of the definition of the approximate mean curvature vector in two terms: in terms of linear operators and in terms of regularity of the varifold. We then extend the results to the approximate second fundamental form. Finally, we prove some additional comparison principles satisfied by the motion of points cloud by mean curvature (in the discrete and the continuous cases). |
