This two-week programme will be held from 06 to 17 July 2026. The first week features a series of lecture courses primarily aimed at early-career researchers. The second week is a research conference.
A central theme of the meeting is Functorial Quantum Field Theories beyond TQFTs and the Segal-Stolz–Teichner programme.
The event will highlight recent developments in extended functorial field theories; analytic structures in quantum field theory, including higher categorical analogues of von Neumann algebras and Hilbert spaces; categorified geometric structures, such as higher vector bundles and stringor bundles; and, supersymmetry and its role in generalized cohomology theories.
The workshop and conference hope to provide an opportunity to advance the interface between homotopy theory, operator algebras, and quantum field theory.
