摘要
设 G 是还原群,X 是代数闭域 k 上的正特征代数曲线。我们证明了 X 上的驯服 G 局域系统和 Frobenius 扭转 \(X'\)上的对数 G-Higgs 束的非阿贝尔霍奇对应关系。为了全面描述非紧凑情况下的对应关系,我们引入了准群方案语言来建立对应关系。
Tame parahoric nonabelian Hodge correspondence in positive characteristic over algebraic curves
Let G be a reductive group, and let X be an algebraic curve over an algebraically closed field k with positive characteristic. We prove a version of nonabelian Hodge correspondence for tame G-local systems over X and logarithmic G-Higgs bundles over the Frobenius twist \(X'\). To obtain a full description of the correspondence for the noncompact case, we introduce the language of parahoric group schemes to establish the correspondence.
