The aim of this workshop is to bring together researchers from both physics- in topological quantum field theory, high energy physics, and condensed matter- and mathematics- higher categories, representation theory, and topology- to report on recent progress and open questions in the study of generalised notions of symmetry. There have been significant recent developments in exploring categorical symmetries in each of these fields, so the time is ripe to bring researchers from these communities together to promote a cross-fertilisation of ideas and insights. The primary theme of the workshop is to develop a common framework for defining and working with categorical symmetry in quantum field theory.

3-8 September 2023: School


  • Applied Cobordism Hypothesis - David Jordan (University of Edinburgh)
  • Non-invertible Symmetries - Shu-Heng Shao (Stony Brook University)
  • The Mathematics of TQFTs and Defects - Constantin Teleman (University of California Berkeley)
  • Symmetry Categories 101 - Michele Del Zotto (Uppsala Universitet)


This will be a hybrid mode event: most speakers will be in-person, with some virtual speakers; about half of the participants will be in-person, and talks will also be live-streamed on Zoom. Videos will be archived on a youtube channel

Immediately preceeding GCS2023 there are two distinct events, a Nordita Program (August 14-25) and a conference in Regensburg (August 14-18). Although these events are logically separate, with different organizing teams and registrations, we purposefully scheduled these events close to each other to avoid too many transatlantic flights.
