Interior singularity and branching of geodesics in real-analytic sub-Riemannian manifolds

Tommaso Rossi, Alec Jacopo Almo Schiavoni Piazza, Alessandro Socionovo

We study the regularity and branching of strictly abnormal minimizing geodesics in sub-Riemannian geometry. We construct examples of real-analytic sub-Riemannian manifolds admittin…
