Commuting Line Defects At
Davide Gaiotto, Gregory W. Moore, Andrew Neitzke +1
We explain the physical origin of a curious property of algebras which encode the rotation-equivariant fusion ring of half-BPS line defects in four-dimen…
The quantum UV-IR map for line defects in -type class theories
Andrew Neitzke, Fei Yan
We consider the quantum UV-IR map for line defects in class theories of -type. This map computes the protected spin character which counts framed BPS states w…
Exact WKB and the quantum Seiberg-Witten curve for 4d pure Yang-Mills, Part I: Abelianization
Fei Yan
We investigate the exact WKB method for the quantum Seiberg-Witten curve of 4d pure Yang-Mills, in the language of abelianization. The relevant differential equation…
Factorized class theories and surface defects
Behzat Ergun, Qianyu Hao, Andrew Neitzke +1
It is known that some theories of class are actually factorized into multiple decoupled nontrivial four-dimensional theories. We propose a way of constructing examples of…
-nonabelianization for line defects
Andrew Neitzke, Fei Yan
We consider the -nonabelianization map, which maps links in a 3-manifold to links in a branched -fold cover . In quantum field theory t…
Decorated Symmetry Defects and Their Time-Reversal Anomalies
Clay Cordova, Kantaro Ohmori, Shu-Heng Shao +1
We discuss an isomorphism between the possible anomalies of -dimensional quantum field theories with unitary global symmetry, and those of -dimensional q…
