AI总结:
本文在遍历群作用背景下引入参数化Kähler类,证明其可完全刻画Zariski稠密可测上闭链直至上同调等价。
摘要:
设$Γ$为有限生成群,$(X,μ_X)$为遍历标准Borel概率$Γ$-空间。假设$G$是Hermitian对称空间等距群的单位连通分支。给定Zariski稠密可测上闭链$σ:Γ\ imes X \ ightarrow G$,我们定义参数化Kähler类的概念,并证明它完全决定了该上闭链,直到上同调等价。
英文摘要:
Let $Γ$ be a finitely generated group and let $(X,μ_X)$ be an ergodic standard Borel probability $Γ$-space. Suppose that $G$ is the connected component of the identity of the isometry group of a Hermitian symmetric space. Given a Zariski dense measurable cocycle $σ:Γ\times X \rightarrow G$, we define the notion of parametrized Kähler class and we show that it completely determines the cocycle up to cohomology.x
