论文摘要
代数叶子在固定程度和中心奇异性的P2上的模量空间具有许多不可还原成分。我们找到了针对有理函数定义的Brieskorn模块的基础，并证明了下拉背叶构成模量空间的不可约组件。主要工具是两个变量，周期积分和Brieskorn模块中有理函数的Picard-Lefschetz理论。
The moduli space of algebraic foliations on P2 of a fixed degree and with a center singularity has many irreducible components. We find a basis of the Brieskorn module defined for a rational function and prove that set of pull-back foliations forms an irreducible component of the moduli space. The main tools are the Picard-Lefschetz theory of a rational function in two variables, period integrals, and the Brieskorn module.
