论文摘要
我们表征了子集$ e \ subset \ mathbb {r} $，其中存在一个连续的实际有价值函数$ f：\ mathbb {r} \ to \ mathbb {r} $，这样唇$ f $ abor theveration whorder，lip $ f $ f $ abinite at in $ e $ e $ e $。
We characterize the subsets $E \subset \mathbb{R}$ for which there exists a continuous real valued function $f: \mathbb{R}\to\mathbb{R}$ such that lip $f$ is finite everywhere and Lip $f$ is infinite exactly on $E$.
