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.

Nakajima quiver varieties are moduli spaces of representations of quivers. They are interesting both from a geometric and representation-theoretic point of view.  In this talk I will first provide the necessary background in geometric invariant theory, then I will recall the definitions of quiver representation, double and framed quiver. Once the Nakajima quiver varieties are defined, I will provide examples with quivers of type An. In conclusion I will shortly explain how these varieties can be used in the representation theory of quantum affine algebras.
