光滑紧algebraic varieties构型空间的一个纯性定理

A purity theorem for configuration spaces of smooth compact algebraic varieties

A. G. Gorinov

摘要:

B.东太郎表明\cite{totaro}的合理上同调的配置空间的顺利复杂的投影品种是同构的代数的$E_2$长期的勒雷谱序列对应的开放嵌入的配置空间到笛卡尔权力。本文证明了同构可以被选择为与混合Hodge结构相容。特别地,我们证明了光滑复射影簇的位形空间上的混合Hodge结构是纯Hodge结构的直和。

英文摘要:

B. Totaro showed \cite{totaro} that the rational cohomology of configuration spaces of smooth complex projective varieties is isomorphic as an algebra to the $E_2$ term of the Leray spectral sequence corresponding to the open embedding of the configuration space into the Cartesian power. In this note we show that the isomorphism can be chosen to be compatible with the mixed Hodge structures. In particular, we prove that the mixed Hodge structures on the configuration spaces of smooth complex projective varieties are direct sums of pure Hodge structures.
