对称Quandles的同调群与链环和面链环的余圈不变量

Homology Groups of Symmetric Quandles and Cocycle Invariants of Links and Surface-links

Seiichi Kamada, Kanako Oshiro

摘要:

引入了具有好对合的quandle及其同调群的概念。Carter等人定义了定向链和定向面链的quandle上循环不变量。通过使用好的对合,quandle cocyle不变量可以被定义为不一定定向或可定向的链接和表面链接。该不变量可用于估计非可定向曲面链环的最小三重点数。

英文摘要:

We introduce the notion of a quandle with a good involution and its homology groups. Carter et al. defined quandle cocycle invariants for oriented links and oriented surface-links. By use of good involutions, quandle cocyle invariants can be defined for links and surface-links which are not necessarily oriented or orientable. The invariants can be used in order to estimate the minimal triple point numbers of non-orientable surface-links.
