Bonjour tout le monde, Je suis pas à Villetaneuse aujourd'hui, mais je me connecterai en visio. À bientôt, Aurélien. Le 29/01/2026 à 20:55, Groupe de travail catégories a écrit :
Hi!
Tomorrow at 10:30 in B107 (we should have a key this time, even if it isn't the one that was lost...) Quentin will be continuing the reading group on Synthetic Differential Geometry. Last time he had told us about C-oo-rings, and this time he will be explaining how to build a site out of these which will house a model of SDG.
I won't be there unfortunately, but Jonas still knows the login details so he should be able to get the BBB working: https://bbb.lipn.univ-paris13.fr/b/rog-vao-uwm-s2j
Next week we may have Christian telling us something about K-theory if he is available (let me know @Christian)
Best, Morgan
