Higher-form symmetries as higher automorphism bundles
Alonso Perez-Lona
The notion of global higher-form symmetries has received much attention, but leaves room for a more systematic mathematical formulation. In this article, we highlight the concept o…

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…

Decomposition in 2d non-invertible gaugings
Alonso Perez-Lona
We extend the decomposition conjecture to 2d quantum field theories with a gauged symmetry category for a finite-dimensional semisimple Hopf algebra with $\text…
