Abstract
We characterize the denseness of the singular set of the distance function from a -hypersurface in terms of an inner ball condition and we address the problem of the existence of viscosity solutions of the Eikonal equation whose singular set (i.e. set of non-differentiability points) is not no-where dense.

具有稠密奇异集的距离函数
摘要
我们从一个 -超曲面在内球条件方面,我们解决了 Eikonal 方程的粘度解存在的问题,其奇异集(即非可微点集)不是无处稠密的。
