Dear colleagues, with apologies for the very short notice: A small workshop will take place in Copenhagen May 15-19: "Beyond Finite Sets -- Homotopy Theory and Combinatorics" https://geotop.math.ku.dk/calendar/beyond-finite-sets/ The confirmed speakers are Mathieu Anel, Ulrik Buchholtz, Robert Burklund, Jesper M??ller, Nima Rasekh, Egbert Rijke, Emily Roff, Maru Sarazola, Jan Steinebrunner, Simon Willerton, and a few more will be added and/or improvised. The precise programme will be determined in real time, but we plan to have traditional-format talks in the mornings and more flexible and interactive formats in the afternoon. For logistic purposes, registration is required (at the web page), but feel free also to contact the organisers. Best regards, Maxime Ramzi and Joachim Kock.
