有效非典型交及其在轨道闭包中的应用

Effective atypical intersections and applications to orbit closures

Gregorio Baldi, David Urbanik

AI总结:

本文提出超越 Zilber-Pink 猜想的统一框架处理单值化非典型交,给出平移曲面层中极大非典型轨道闭包有限性的新证明,并设计可计算非典型轨道闭包和微分方程非典型特殊轨迹的有效算法。

摘要:

我们提出一个统一的框架来处理单值化非典型交,该框架超越了通常的 Zilber-Pink 猜想。特别地,我们获得了平移曲面 $Ω\mathcal{M}_g (κ)$ 每个层中极大非典型轨道闭包有限性的一个新证明,该结果由 Eskin、Filip 和 Wright 给出。我们还描述了一个具体算法,原则上可在计算机上实现,该算法可证明地计算所有在 Filip 所述意义下为“非典型”的极大轨道闭包。同样的方法还给出了一个用于计算与微分方程组相关的非典型特殊轨迹的一般算法,特别地,为混合 Hodge 结构的变分给出了几何 Zilber-Pink 猜想的一个有效且不依赖 o-minimal 理论的证明。

英文摘要:

We propose a new unifying setting for dealing with monodromically atypical intersections that goes beyond the usual Zilber-Pink conjecture. In particular, we give a new proof of finiteness of the maximal atypical orbit closures in each stratum of translation surfaces $Ω\mathcal{M}_g (κ)$, as given by Eskin, Filip, and Wright. We also describe a concrete algorithm, implementable in principle on a computer, which provably computes all maximal orbit closures which are ``atypical'' in a sense described by Filip. The same methods also give a general algorithm for computing atypical special loci associated to systems of differential equations, and in particular give an effective and o-minimal free proof of the geometric Zilber-Pink conjecture for variations of mixed Hodge structures.
