Gauging Noninvertible Defects: A 2-Categorical Perspective
Thibault D. Décoppet, Matthew Yu
We generalize the notion of an anomaly for a symmetry to a noninvertible symmetry enacted by surface operators using the framework of condensation in 2-categories. Given a multifus…

What bordism-theoretic anomaly cancellation can do for U
Arun Debray, Matthew Yu
We perform a bordism computation to show that the U-duality symmetry of 4d supergravity could have an anomaly invisible to perturbative meth…

Feynman Diagrams in Four-Dimensional Holomorphic Theories and the Operatope
Kasia Budzik, Davide Gaiotto, Justin Kulp +2
We study a class of universal Feynman integrals which appear in four-dimensional holomorphic theories. We recast the integrals as the Fourier transform of a certain polytope in the…
