Sage Days 128: combinatorics, number theory, dynamical systems and geometry

From February 10th to 14th 2025 in Maison de la nature du bassin d'Arcachon (France) in the parc ornithologique du Teich.

A limit of 25 participants. Half of the places are reserved for PhD Students/Postdoc. We aim for a diversity and parity of participants.

Main thematics will be combinatorics, number theory, dynamical systems and geometry. Developers for software SageMath, PARI/GP, flint and others projects have confirmed participation.

If you wish to come, get in touch with the organizers by e-mail.
