Fiber 2-Functors and Tambara-Yamagami Fusion 2-Categories

Thibault D. Décoppet, Matthew Yu

We introduce group-theoretical fusion 2-categories, a strong categorification of the notion of a group-theoretical fusion 1-category. Physically speaking, such fusion 2-categories…

Semi-Chiral Operators in 4d $N = 1$ Gauge Theories

Kasia Budzik, Davide Gaiotto, Justin Kulp +3

We discuss the properties of quarter-BPS local operators in four dimensional $N = 1$ supersymmetric Yang-Mills theory using the formalism of holomorphic twists. We study loop…

Adams spectral sequences for non-vector-bundle Thom spectra

Arun Debray, Matthew Yu

When $R$ is one of the spectra $ku$ , $ko$ , $tmf$ , $MTSpin^{c}$ , $MTSpin$ , or $MTString$ , there is a standard approach to computi…
