论文摘要
我们研究了某些公式给出的表面的几何特性。特别是,我们沿着奇异曲率计算了奇异曲率和限制沿着奇异点的正常曲率,该点由第一类的奇异点组成。此外,我们研究光滑地图的单数点。
We investigate geometric properties of surfaces given by certain formulae. In particular, we calculate the singular curvature and the limiting normal curvature of such surfaces along the set of singular points consisting of singular points of the first kind. Moreover, we study fold singular points of smooth maps.
