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.

By the Beauville-Bogomolov decomposition theorem, hyper-Kaehler manifolds form building blocks of compact Kaehler manifolds whose canonical bundle is numerically trivial. By fundamental works of Matsushita, Hwang, Voisin and many others, the study of Lagrangian families is important to understand properties of hyper-Kaehler manifolds. In this presentation, after recalling some basic notions in complex geometry and algebraic geometry, I will present basic properties and examples of hyper-Kahler manifolds, with an emphasis on their algebraic cycles which are Lagrangian. If time permits, I would also present our recent works on Abel-Jacobi maps of Lagrangian families.
