同维一叶网是有限多个同维一叶在一般位置上的构型。许多经典理论都是围绕阿贝尔关系的概念发展而来的:阿贝尔关系是定义网络的叶层的第一个积分之间的函数关系,让人想起经典代数几何中的阿贝尔加法定理。给定网络的阿贝尔关系形成一个有限维向量空间,其维数(网络的秩)以Castelnuovo数p(n,k)为界,其中n是周围空间的维数,k是定义网络的树叶数。腹板几何中的一个基本问题是异常腹板的分类,即极大秩的腹板不等价于射影曲线的对偶。最近,J.-M.Trepreau证明了对于n>2和k>2n-1没有例外的k网。在维数2中,对于任意k有例外的k-网的例子,分类问题是开放的。本文对定义在紧致复杂曲面上的例外完全可分解拟线性(CDQL)网进行了全局分类。根据定义,CDQL(k+1)-网由k个线性叶理和一个非线性叶理叠加而成。例如,我们证明了直到射影变换,在射影平面上有四个可数族和十三个零星例外CDQL网。

英文摘要:
  Codimension one webs are configurations of finitely many codimension one foliations in general position. Much of the classical theory evolved around the concept of abelian relation: a functional relation among the first integrals of the foliations defining the web reminiscent of Abel's addition theorem in classical algebraic geometry. The abelian relations of a given web form a finite dimensional vector space with dimension (the rank of the web) bounded by Castelnuovo number p(n,k) where n is the dimension of the ambient space and k is the number of foliations defining the web. A fundamental problem in web geometry is the classification of exceptional webs, that is, webs of maximal rank not equivalent to the dual of a projective curve. Recently, J.-M. Trepreau proved that there are no exceptional k-webs for n>2 and k > 2n-1. In dimension two there are examples of exceptional k-webs for arbitrary k and the classification problem is wide open.   In this paper, we classify the exceptional Completely Decomposable Quasi-Linear (CDQL) webs globally defined on compact complex surfaces. By definition, the CDQL (k+1)-webs are formed by the superposition of k linear foliations and one non-linear foliation. For instance, we show that up to projective transformations there are exactly four countable families and thirteen sporadic exceptional CDQL webs on the projective plane.
