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.

RésumeA surface is said to be hyperbolic, if it looks locally like the hyperbolic plane. In this talk, I will explain how to randomly pick a hyperbolic surface, and explore its topology and geometry. In particular, we will see that the average length of the shortest closed geodesic (the systole) on a random hyperbolic surface is approximately 1.61498 when the genus (the number of ``holes'' on the surface) goes to infinity.
