摘要:

在有理尖点平面曲线分类的开放问题中,必须找到曲线C的奇异类型的良好必要条件,以便C退出。出于研究的塞伯格-威滕不变量的正常表面奇点的链接是一个合理的同源领域,我们已经找到了很好的候选人,这样的必要条件。本文研究了这一相容性条件,并证明了它适用于对数Kodaira维数严格小于2的所有曲线。

英文摘要:

In the open problem of classification of rational cuspidal plane curves it is essential to find good necessary conditions on the type of singularities of a curve C in order C to exit. Motivated by the study of the Seiberg-Witten invariant of normal surface singularities whose link is a rational homology sphere we have found good candidates for such necessary conditions. In this paper we study this compatibility conditions and proved them for all curves whose logarithmic Kodaira dimension is strictly less than 2.
