我们研究具有简单奇点到等奇异变形的复杂平面射影六次曲线。结果表明,当且仅当对应的曲线对是微分同胚时,两条这样的曲线是变形等效的。概述了枚举所有变形类别的方法,并考虑了一些示例,包括经典的 Zariski 对;特别是,发现了有希望的同胚对而非微分同胚对的候选者。
We study complex plane projective sextic curves with simple singularities up to equisingular deformations. It is shown that two such curves are deformation equivalent if and only if the corresponding pairs are diffeomorphic. A way to enumerate all deformation classes is outlined, and a few examples are considered, including classical Zariski pairs; in particular, promising candidates for homeomorphic but not diffeomorphic pairs are found.
