论文摘要
本文认为,逐与塑形的等效关系对平滑流形的差异性。在维度2及更高版本中,表明没有borel方法可以连接完整的数值不变性。在维度5及更高版本中,表明等效关系不是borel,实际上是完全分析的。
The paper considers the equivalence relation of conjugacy-by-homeomorphism on diffeomorphisms of smooth manifolds. In dimension 2 and above it is shown that there is no Borel method of attaching complete numerical invariants. In dimension 5 and above it is shown that the equivalence relation is not Borel, and in fact is complete analytic.
