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.

The aim of this presentation is to introduce variational aspects of geometric analysis through the scope of harmonic maps.

I will recall well-known properties of harmonic functions in Euclidean space to motivate the study of harmonic maps between Riemannian manifolds from a variational perspective. The focus will be on three main aspects: existence, regularity and bubbling phenomena associated with energy concentration along sequences of harmonic maps from surfaces. These elements will be explored to highlight their significance in understanding the asymptotic behavior of harmonic maps.
