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.

RésumeHyperbolic structures on a surface give rise to injective homomorphisms with discrete image from its fundamental group to SL(2,R). This is the object of study of classical Teichmüller Theory. In this talk, we will look for homomorphisms of the fundamental group of the surface to SL(3,R). To do so we will endow the space of such homomorphisms with a topology. It has three connected components; among them is the "Hitchin component" which has a nice geometric interpretation. We will particularly focus on injective homomorphisms with discrete image. This is the subject of Higher Teichmüller Theory.
