We encourage the presence and participation of students and young researchers.

2.1 Propositions of talks

(no order for the moment, we will decide together on sunday 29th)

Lucas Noël et Vincent Ferrarri en duo sur une généralisation du principe d’incertitude fractale en dimension supérieure https://arxiv.org/abs/2305.05022. On mentionnera également deux applications récentes qui permettent d’étendre les résultats de support des mesures semiclassiques, pour les automorphismes hyperboliques du tore https://arxiv.org/abs/2410.13449 ou pour le flot géodésique sur des variétés hyperbolique https://arxiv.org/abs/2503.01528 en s’inspirant des techniques initiées par https://arxiv.org/abs/1705.05019. L’article est long et on devra probablement sélectionner les parties pertinentes, ne serait-ce que pour passer un peu de temps pour mentionner les applications.
Duo:
- Damien Gayet “Que vaut la longueur de la systole d’une surface hyperbolique compacte aléatoire ? (d’après M. Mirzakhani). "
- Julien Boulanger: sur le thème de l’article d’Eskin et Mirzakhani sur le comptage des géodésiques fermées sur l’espace de modules des surfaces hyperboliques suivant : https://arxiv.org/abs/0811.2362
Tristan Humbert/Louis Beaufort en duo sur l’article de Jonathan DeWitt, Dmitry Dolgopyat: https://arxiv.org/abs/2503.06855 ,
Roméo Tabaoda/Julien Moy en duo sur les travaux de Alexander Strohmaier, Steve Zelditch, notamment le premier article https://arxiv.org/abs/1808.08425
Martin Vogel : conjecture de Landis
Charlotte Dietze sur le sujet de son choix.
Sébastien Gouezel propose de présenter: exposé introductif autour des questions de surface plat et/ou de pseudo-Anosov. Des connections entre les deux, des questions qui se posent.
Maria Teresa propose de faire un exposé sur le papier suivant de Kouichi Taira https://arxiv.org/abs/2004.07547

Just look at the view and think or discuss about mathematics.
Look at mountain flowers. This will the full season of blowing flowers. Here is a list and a useful app. Make a tour around Peyresq and try to recognize them!
Walk in the moutain around Peyresq. Bring good clothes and shoes. Here is a map . There is a local summit (2693m = Peyresq + 1170m): "le grand coyer" and a more local one (2157m = Peyresq + 620m) "le courradour". There is a small cave to visit, bring your lights. La grotte de Meailles
Climbing at annot, pictures, topo.

Mountain bike. Bring your mountain bike (there will be 3 places on the minibus). Here are the topo.
Look for fossiles.
