由对称群的自同构引起的齐次quandles

Homogeneous quandles arising from automorphisms of symmetric groups

Akihiro Higashitani, Hirotake Kurihara

摘要:

Quandle是一个有一个二元运算的代数系统,但它与群有很大的不同。Quandle起源于纽结理论,并且与对称空间理论有着良好的关系,因此从这两个领域的观点来看,Quandle都得到了很好的研究。本文研究一类特殊的quandles,称为广义Alexander quandles $Q(G,ψ)$,它是由群$G$及其群自同构$ψ$定义的.我们开发的quandle不变量广义亚历山大quandles。证明了由对称群$\Sf_n$产生的广义Alexander quandles与$\Sf_n$的共轭类之间存在一一对应关系,并讨论了$3 \leq n \leq 30$与$n \neq 6,15$的情形.

英文摘要:

Quandle is an algebraic system with one binary operation, but it is quite different from a group. Quandle has its origin in the knot theory and good relationships with the theory of symmetric spaces, so it is well-studied from points of view of both areas. In the present paper, we investigate a special kind of quandles, called generalized Alexander quandles $Q(G,ψ)$, which is defined by a group $G$ together with its group automorphism $ψ$. We develop the quandle invariants for generalized Alexander quandles. As a result, we prove that there is a one-to-one correspondence between generalized Alexander quandles arising from symmetric groups $\Sf_n$ and the conjugacy classes of $\Sf_n$ for $3 \leq n \leq 30$ with $n \neq 6,15$, and the case $n=6$ is also discussed.
