拼接图与拼接商曲面奇点

Splice diagrams and splice-quotient surface singularities

Jonathan Wahl

摘要:

目前的工作将出现在Celebratio数学卷在荣誉沃尔特诺依曼。我们总结的结果和方法,从我们的长期合作与诺依曼,特别是动机引入拼接图来定义奇点的拼接类型和拼接商奇点。讨论了Casson不变猜想和Milnor Fiber猜想,以及关于具有积分同调球面链的超曲面和完全相交奇点的一些公开问题。

英文摘要:

The current work will appear in a Celebratio Mathematica volume in honor of Walter Neumann. We summarize results and methods from our long-time collaboration with Neumann, especially the motivation for the introduction of splice diagrams to define singularities of splice type and splice-quotient singularities. The Casson Invariant Conjecture and Milnor Fiber Conjectures are discussed, as well as some open questions about hypersurface and complete intersection singularities with integral homology sphere link.
