Generic singularities of line fields on 2D manifolds
Ugo Boscain, Ludovic Sacchelli, Mario Sigalotti
Generic singularities of line fields have been studied for lines of principal curvature of embedded surfaces. In this paper we propose an approach to classify generic singularities…

Intrinsic random walks in Riemannian and sub-Riemannian geometry via volume sampling
Andrei Agrachev, Ugo Boscain, Robert Neel +1
We relate some basic constructions of stochastic analysis to differential geometry, via random walk approximations. We consider walks on both Riemannian and sub-Riemannian manifold…
