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…

Quantum parameters of the geometric Langlands theory

Yifei Zhao

Fix a smooth, complete algebraic curve $X$ over an algebraically closed field $k$ of characteristic zero. To a reductive group $G$ over $k$ , we associate an algebraic stack $\opera…
