Exact WKB and the quantum Seiberg-Witten curve for 4d $N = 2$ pure $S U (3)$ Yang-Mills, Part I: Abelianization

Fei Yan

We investigate the exact WKB method for the quantum Seiberg-Witten curve of 4d $N = 2$ pure $S U (3)$ Yang-Mills, in the language of abelianization. The relevant differential equation…

Factorized class $S$ theories and surface defects

Behzat Ergun, Qianyu Hao, Andrew Neitzke +1

It is known that some theories of class $S$ are actually factorized into multiple decoupled nontrivial four-dimensional $N = 2$ theories. We propose a way of constructing examples of…

$q$ -nonabelianization for line defects

Andrew Neitzke, Fei Yan

We consider the $q$ -nonabelianization map, which maps links $L$ in a 3-manifold $M$ to links $L$ in a branched $N$ -fold cover $M$ . In quantum field theory t…
