On the SymTFTs of Finite Non-Abelian Symmetries
Oren Bergman, Jonathan J. Heckman, Max Hübner +3
The -dimensional symmetry topological field theory (SymTFT) of a -dimensional absolute quantum field theory (QFT) provides a topological characterization of s…

von Neumann Subfactors and Non-invertible Symmetries
Xingyang Yu, Hao Y. Zhang
We use the language of von Neumann subfactors to investigate non-invertible symmetries in two dimensions. A fusion categorical symmetry , its module category $\mathcal…

Total instanton restriction via multiverse interference: Noncompact gauge theories and (-1)-form symmetries
Alonso Perez-Lona, Eric Sharpe, Xingyang Yu +1
In this note we consider examples of decomposition (in which a local QFT is equivalent to a disjoint union of multiple independent theories, known as universes) where there is a co…
