The quantum torus as an $E_{M}$ -category

Lin Chen, Yifei Zhao

Given an oriented $2$ -manifold $M$ , a locally constant sheaf of lattices $Λ$ over $M$ , and a pointed morphism $q : B^{2} Λ \to B^{4} C^{\times}$ , we define…

Lifting representations of finite reductive groups: a character relation

Jeffrey D. Adler, Michael Cassel, Joshua M. Lansky +2

Given a connected reductive group $G ~$ over a finite field $k$ , and a semisimple $k$ -automorphism $ε$ of $G ~$ of finite order, let $G$ denote the connected…
