4d Maxwell on the Edge: Global Aspects of Boundary Conditions and Duality
Adrien Arbalestrier, Riccardo Argurio, Giovanni Galati +1
We revisit Maxwell theory in 4d with a boundary, with particular attention to the global properties of the boundary conditions, both in the free (topological) and interacting (conf…

Global variants of theories and Calogero-Moser systems
Jeremías Aguilera Damia, Riccardo Argurio, Antoine Bourget +2
Global variants of four-dimensional gauge theories are specified by their spectrum of genuine Wilson-'t Hooft line operators. The choice of global variant has significant consequen…

U(1) Gauging, Continuous TQFTs, and Higher Symmetry Structures
Adrien Arbalestrier, Riccardo Argurio, Luigi Tizzano
Quantum field theories can exhibit various generalized symmetry structures, among which higher-group symmetries and non-invertible symmetry defects are particularly prominent. In t…
