| Description | Le séminaire des doctorant.e.s est l'occasion pour les doctorant.e.s de présenter des résultats et des problématiques dignes d'intérêt devant un public de non-spécialistes. L'ambiance y est informelle ; poser des questions naïves est encouragé, et les questions moins naïves sont bienvenues dans la mesure où elles n'entravent pas le bon déroulement de l'exposé. Chaque jeudi à 18h, en alternance entre Jussieu et Sophie Germain. The PhD seminar is an opportnuity for PhD students to present results and topics worthy of interest in front of a non-specialist audience. The mood is informal ; asking naive questions is highly encouraged and less naive questions are also welcomed, as long as they don't intefere with the smoothness of the talk. Every Thursday at 6pm, alternating between Jussieu and Sophie Germain. |

| Résume | Any subspace S of a metric space M admits an induced length distance, which might not be finite. This is done by defining the distance between two point in S as the supremum of the metric length of the continuous curves in S connecting the points. In this presentation — after an interactive introduction — we discuss what happens in the setting of a surface S embedded in a 3D contact sub-Riemannian manifold M. Finally, we will discuss the behaviour of a stochastic process that can be canonically defined on S, and we illustrate the results with examples. These works are joint work with Davide Barilari, Ugo Boscain and Karen Habermann. |
