Title:
The geometry of a point cloud : a varifold approach.
Abstract: <p>Varifolds represent a natural generalization of manifolds in the measure theoretic sense, they encode a joint distribution of mass and tangents and were introduced mainly as a model for soap films and to solve the plateau problem.<br />
In this talk, we will present recent works of Buet, Leonardi and Masnou on the geometry of varifolds (definition of weak curvatures) with a particular focus on point cloud varifolds, at last we will give a glimpse of how to define a consistent Laplace operator for general measures.</p>
