Bonjour, École polytechnique, LRDE and EPITA are organizing a scientific conference next week, "GETCO: Geometric and Topological Methods in Computer Science". See https://www.lix.polytechnique.fr/~smimram/getco22/ for program etc. Most talks will take place in Amphi 0, except for some parallel sessions in the afternoons which will be in KB404. Even if you are not registered, you're welcome to come and join us for some of the talks. Bien cordialement, for the organisers, Uli Fahrenberg, LRDE
