Séminaires : Phd Seminar - Séminaire des doctorant.e.s

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.

Given a tuple of positive integers (k_1, ..., k_r) such that $k_1 \geq 2$, one can define the associated multiple zeta value (MZV) as a convergent series. Some of the central conjectures in the field concern the linear relations among these numbers, as well as the structure of certain Lie and commutative algebras built from them. In this talk, we will introduce a few basic objects related to MZVs and outline the expected connections with Grothendieck–Teichmüller theory, whose aim is to study the absolute Galois group of the rationals.
