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…

On the topology of

Tommaso Rossi

This paper contains some results about the topology of $\M_{0,n+1}/Σ_n$, where $\M_{0,n+1}$ is the moduli space of genus zero Riemann surfaces with marked points. We show that $\M…

Chain level Koszul duality between the Gravity and Hypercommutative operads

Tommaso Rossi, Paolo Salvatore

Let be the moduli space of genus zero stable curves with -marked points. The collection $\overline{\mathcal{M}}=\{\overline{\mathcal{M}}_{0,…
