引入了quandles的拟平凡性概念，定义了quandles的同调。Quandle上圈不变量在链同伦下是不变的，如果它们与拟平凡Quandle的2-上圈相关联。从而得到了大量的数值链同伦不变量。
We introduce the notion of quasi-triviality of quandles and define homology of quasi-trivial quandles. Quandle cocycle invariants are invariant under link-homotopy if they are associated with 2-cocycles of quasi-trivial quandles. We thus obtain a lot of numerical link-homotopy invariants.
