$p$ -torsion étale sheaves on the Jacobian of a curve

Yifei Zhao

Suppose $X$ is a smooth, proper, geometrically connected curve over $F_{q}$ with an $F_{q}$ -rational point $x_{0}$ . For any $F_{q}^{\times}$ -character $σ$ of $π_1(X…

Extensions by $K_{2}$ and factorization line bundles

James Tao, Yifei Zhao

Let $X$ be a smooth, geometrically connected curve over a perfect field $k$ . Given a connected, reductive group $G$ , we prove that central extensions of $G$ by the sheaf $\mathbf K…
