论文摘要
我们研究了第一个额叶的非分类奇异点附近的主要曲线和主要向量的行为。作为应用程序，我们将肋骨转换的概念扩展到具有单数点的正面。
We investigate behavior of principal curvatures and principal vectors near a non-degenerate singular point of the first kind of frontals. As an application, we extend the notion of Ribaucour transformations to frontals with singular points.
