| 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 | Reducibility of quasi-periodic cocyles is closely related to absolutely continuous spectrum of discrete Schrodinger operators. Local reducibility have been studied by KAM theory, while global reducibility can be studied by renormalization and KAM theory. In this talk, we will talk about a global reducibility result on quasi-periodic cocycles. If time permitting, we will also talk about hyperbolicity of renormalization. |
