论文摘要
在本说明中，我们表明平滑地图的等级是Bi-Lipschitz触点不变。结果，第一个董事会符号及其长度是Bi-lipschitz接触不变的。我们还给出了一个反例，表明光滑地图的董事会象征不是Bi-lipschitz的右不变。
In this note we show that the rank of a smooth map is a bi-Lipschitz contact invariant. As a consequence, the first Boardman symbol and its length are bi-Lipschitz contact invariants. We also give a counterexample showing that Boardman symbol of a smooth map is not a bi-Lipschitz right invariant.
