Cyclic duality for slice and orbit 2-categorie

Vortragende: Julius Krähmer, Universität Dresden
Einladende: Karl-Hermann Neeb

Abstract:
After a minicouse on simplicial sets I will explain how they can be extended to
duplicial and paracyclic ones, and why I and a few others care about these. The
main topic will then be one possible answer to the question why the more exotic
index categories controlling the latter are self-dual while the simplicial
category is not. [Based on joint work with John Boiquaye and Philipp Joram].
