论文摘要
我们构建了第一个差异性的例子，这些例子被扭曲成$ c^r $ diffemormormormiss，但在相应的$ c^s $ diffeomormormormormisms中未经证实，其中$ r <s $。对于封闭的间隔，进行了此明确的结构，$ r = 1 $和$ s = 2 $。
We build the first examples of diffeomorphisms that are distorted in a group of $C^r$ diffeomorphisms yet undistorted in the corresponding group of $C^s$ diffeomorphisms, where $r < s$. This explicit construction is performed for the closed interval, $r = 1$ and $s = 2$.
