Flex轨迹参数化平面三次与三个共线的共临界点下的投影,和哥特式轨迹产生于二次微分与零的纤维的投影和极点的共临界点。Flex和Gothic轨迹提供了模空间的一个原始的、完全测地的子簇和Teichmüller动力学中的新不变簇的第一个例子,如McMullen-Mukamel-Wright所发现的。本文确定了挠轨线的除子类以及哥特轨线上的各种重言式交数。对于哥特式轨迹的情况下,我们的结果证实了数值的陈Möller-Sauvaget猜想计算的李雅普诺夫指数的总和不变品种通过交叉理论。
The flex locus parameterizes plane cubics with three collinear cocritical points under a projection, and the gothic locus arises from quadratic differentials with zeros at a fiber of the projection and with poles at the cocritical points. The flex and gothic loci provide the first example of a primitive, totally geodesic subvariety of moduli space and new-invariant varieties in Teichmüller dynamics, as discovered by McMullen–Mukamel–Wright. In this paper we determine the divisor class of the flex locus as well as various tautological intersection numbers on the gothic locus. For the case of the gothic locus our result confirms numerically a conjecture of Chen–Möller–Sauvaget about computing sums of Lyapunov exponents for-invariant varieties via intersection theory.
