| 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 | Algebraic varieties are geometric objects that are given as solutions to polynomial equations. Algebraic stacks are generalizations of algebraic varieties and they often appear as solutions to moduli questions. We count points on algebraic stacks. This may give a new insight to a famous conjecture from analytic number theory on the number of certain field extensions of the field of rational numbers. |
