ODELIX — Thematic fall program 2025

WelcomeTeamPublicationsSoftwareEventsJobsInternships

During the fall of 2025, between Wednesday, November 12 and Wednesday, December 10, we organize a thematic program at LIX around the topics of the Odelix project. The main aim is to favor exchanges on the level of our students in a bit more relaxed format than a short conference.

The thematic program englobes the usual MAX seminar, typically on Mondays, and we plan to have further talks by students and other interested researchers. Please feel free to contact Joris van der Hoeven if you wish to participate or give a talk in this program.

Program

All talks are planned in the publicly accessible conference rooms (indicated in the timetable below) in Bâtiment Alan Turing, Campus de l'École polytechnique, 1, rue Honoré d'Estienne d'Orves, Palaiseau.
