摘要翻译:
研究了具有两个奇点的曲线在点合并时的“泛型”退化。首先,精确地定义了泛型退化的概念。然后,在线性奇异性类型的情况下,提出了一种分类泛型退化可能结果的方法。我们根据初始类型讨论了结果类型的奇性不变量的可能界。特别地,证明了多重性的严格上界,并给出了$\delta=const$碰撞的一个充分条件。

英文摘要:
We study the "generic" degenerations of curves with two singular points when the points merge. First, the notion of generic degeneration is defined precisely. Then a method to classify the possible results of generic degenerations is proposed in the case of linear singularity types. We discuss possible bounds on the singularity invariants of the resulting type in terms of the initial types. In particular the strict upper bound on the resulting multiplicity is proved and a sufficient condition for $\delta=const$ collision is given.
