光滑映射函数空间中判别簇的研究是奇点理论的一个传统和基本的部分。判别簇是函数空间中表示具有非一般奇点的映射的那些点的集合。判别簇的补(即一般映射空间)的拓扑、同伦甚至同调不变量在许多应用中是重要的。然而,在这些困难的奇点理论的全球性问题的进展是相当缓慢的,直到瓦西里耶夫[1]在过去的几年里已经证明了新的视角开辟了奇点理论的方法在纽结理论。
The study of the discriminant variety in a functional space of smooth mappings is a traditional and fundamental part of the theory of singularities. The discriminant variety is the set of those points of the functional space which represent the mappings having nongeneric singularities. The topological, homotopical and even homological invariants of the complement to the discriminant variety (that is, of the space of generic mappings) are important for many applications. However, progress in these difficult global problems of singularity theory was rather slow until Vassiliev [1] over the last few years has demonstrated the new perspectives opened up by the singularity theory approach in knot theory.
