论文摘要
我们表征了正面上正常曲率的扩展性，并给出了这种类型的正面的表示公式。同样，我们还为所有类型的奇点和其他子类别提供了波前的表示。在额叶上进行了一些应用于渐近曲线和曲率线的应用。
We characterize the extendibility of the normal curvature on frontals and we give a representation formula of this type of frontals. Also we give representation formulas for wavefronts on all types of singularities and others sub classes of these. Some applications to asymptotic curves and lines of curvature on frontals are made.
