Dear everyone, It is my pleasure to announce a conference on (oo, n)-Categories and Their Applications, which will take place *April 15-19, 2024* at the University of Utrecht (Netherlands). In the last two decades, (oo, n)-categories have developed into a field with many applications and a growing theory. Our goal in this conference is to bring together people interested in this field, both to discuss recent advances in categorical structures and to connect these to applications in topological field theories, representation theory, topology and geometry. Our conference will feature talks by: Fernando Abellán (NTNU Trondheim) Dimitri Ara (Marseille) Tobias Dyckerhoff (Hamburg) David Gepner (Johns Hopkins, tbc) Dennis Gaitsgory (MPIM Bonn) Rune Haugseng (NTNU Trondheim) Sil Linskens (Bonn) Félix Loubaton (MPIM Bonn) Yuki Maehara (Fukuoka, tbc) Aaron Mazel-Gee (Caltech, tbc) Lyne Moser (Regensburg) Paige North (Utrecht) Joost Nuiten (Toulouse) Viktoriya Ozornova (MPIM Bonn) Nima Rasekh (MPIM Bonn) Martina Rovelli (UMass Amherst) Claudia Scheimbauer (TU München, tbc) Chris Schommer-Pries (Notre Dame) The registration is open on our webpage https://sites.google.com/view/inftyncategories. If you would like to contribute a talk or ask for financial support, please register *before January 15*, and otherwise at your earliest convenience. We hope to see many of you in Utrecht!
