Paolo ________________________________ From: Fabio Gironella <fabio.gironella@univ-nantes.fr> Sent: Friday, January 16, 2026 13:24 Cc: orga-school-homotopy@univ-nantes.fr <orga-school-homotopy@univ-nantes.fr> Subject: Spring school "Khovanov and Floer homotopy" - Nantes - 18th-22nd May 2026 Dear friends and colleagues, We are pleased to announce the spring school "Khovanov and Floer homotopy" at Nantes Université, which will take place from the 18th to the 22nd of May 2026. The school, aimed at Master and PhD students, will focus on recent homotopy methods in low-dimensional and symplectic topology. It will mainly revolve around two mini-courses, of four hours plus an exercise session each. The two courses will be given by Marithania Silvero Casanova<https://marithania.github.io/> (University of Seville), on Khovanov homotopy theory, and by Noah Porcelli<https://sites.google.com/view/noahporcelli/home> (Max Planck Institute, Bonn), on Floer homotopy theory. Beside the two mini-courses, there will be three introductory lessons of one hour each, as well as sessions for short talks. In particular, we welcome proposed short talks from participants who would like to talk about their research during the school. The schedule will be rather light, so enough time will be left for participants to discuss together and discover each other's research interests. Registration is open until February 28th 2026. We will be able to provide accommodation (in twin bedrooms) for a limited number of participants. You can register and apply for funding here<https://springschoolhomotopy-fabiogironella.apps.math.cnrs.fr/registration/registration.html>. More information on the school can be found at this page: https://springschoolhomotopy-fabiogironella.apps.math.cnrs.fr/ Please forward this announcement to colleagues/students who might be interested in attending the spring school. Best regards, Fabio Gironella, Marco Golla, and Stéphane Guillermou (the organisers)
