摘要翻译:
我们证明了给定两个同维数光滑变体之间的一个主态射,这些变体上两个弧的形式邻域之间的诱导态射是一个闭嵌入,其余维数由沿分支子格式的消失顺序给出。

英文摘要:
We show that given a dominant morphism between two smooth varieties of the same dimension, the induced morphism between the formal neighborhoods of two arcs on these varieties is a closed embedding, of codimension given by the order of vanishing along the ramification subscheme.
