关于非临界广义曲线叶理的刻画

On characterizations of nondicritical generalized curve foliations

Evelia R. García Barroso, Marcelo E. Hernandes, M. Fernando Hernández Iglesias

摘要:

我们刻画了具有固定约化分界线的非临界广义曲线叶理。并给出了平面解析曲线是其约化分界线的充分条件。为此,我们引入了一个特殊的表达式为一个给定的1-形式,称为{ \it Weierstrass形式}。然后,利用Weierstrass形式,我们刻画了非临界广义曲线叶理:首先,对于具有单项分界线的叶理,使用复曲面分解;其次,对于具有约化分界线的叶理,使用$GSV$ -指标。在这最后一种情况下的特点,这是我们的主要结果,可以解释在功能的一个极的叶理和一个极的减少分界线。

英文摘要:

We characterize nondicrital generalized curve foliations with fixed reduced separatrix. Moreover, we give suficient conditions when a plane analytic curve is its reduced separatrix. For that, we introduce a distinguished expression for a given 1-form, called {\it Weierstrass form}. Then, using Weierstrass forms, we characterize the nondicritical generalized curve foliations: first, for foliations with monomial separatrix using toric resolution; second, for foliations with reduced separatrix, using the $GSV$-index. In this last case the characterization, which is our main result, could be interpreted in function of a polar of the foliation and a polar of its reduced separatrix.
