论文摘要
在本文中，我们使用Katz引入的方法对双平面曲线的极限进行形式表达。作为一个应用程序，我们给出一个公式，以计算$ c（0）$ c（t）$ c（t）$的顶点c（t）$一个单参数曲线家族，我们表明这些顶点仅取决于该家族的第一个$τ$术语，其中$τ$是$ c（t）$的一般类型。
In this paper we give a formal expression to the limits of dual plane curves by using the method introduced by Katz. As an application, we give a formula to compute the vertices of $C(0)$ a plane curve in $C(t)$ a one-parameter family of plane curves and we show that those vertices depend only on the first $τ$ terms of that family, where $τ$ is the general type of $C(t)$.
