负四点射影直线上秩二联络的模空间上的叶

Foliations on the moduli space of rank two connections on the projective line minus four points

Frank Loray, Masa-Hiko Saito, Carlos T. Simpson

摘要:

我们在$\pp ^1 -{t_1,t_2,t_3,t_4}$上查看秩为2的规则连接的Painlevé VI模空间上的自然叶状结构。这些叶理是纤维化,并解释在nonabelian霍奇过滤,给出了一个证明nonabelian霍奇叶理猜想在这种情况下。两种基本的纤维化产生:从表观奇点,从准抛物丛。我们表明,这些是横向的。冈本的附加对称性,可以被看作是卡茨的中卷积,交换了准抛物线和表观奇异叶理。

英文摘要:

We look at natural foliations on the Painlevé VI moduli space of regular connections of rank 2 on $\pp ^1 -{t_1,t_2,t_3,t_4}$. These foliations are fibrations, and are interpreted in terms of the nonabelian Hodge filtration, giving a proof of the nonabelian Hodge foliation conjecture in this case. Two basic kinds of fibrations arise: from apparent singularities, and from quasiparabolic bundles. We show that these are transverse. Okamoto's additional symmetry, which may be seen as Katz's middle convolution, exchanges the quasiparabolic and apparent-singularity foliations.
