Quandles的自同构群

Automorphism groups of Quandles

M. Elhamdadi, J. MacQuarrie, R. Restrepo

摘要:

证明了n元二面体quandle的自同构群与mod n整数的仿射群同构,并得到了该quandle的内自同构群。文[9]给出了阶小于或等于小于5的quandles(直至同构)的自同构群。借助Maple软件,我们计算了文[4]附录中所列的全部73个六阶quandle的内群和自同构群。由于quandles的自同构的计算涉及到quandles的分类问题,我们还描述了一个在C中实现的算法,用于计算所有quandles(同构)的顺序小于或等于9。

英文摘要:

We prove that the automorphism group of the dihedral quandle with n elements is isomorphic to the affine group of the integers mod n, and also obtain the inner automorphism group of this quandle. In [9], automorphism groups of quandles (up to isomorphisms) of order less than or equal to 5 were given. With the help of the software Maple, we compute the inner and automorphism groups of all seventy three quandles of order six listed in the appendix of [4]. Since computations of automorphisms of quandles relates to the problem of classification of quandles, we also describe an algorithm implemented in C for computing all quandles (up to isomorphism) of order less than or equal to nine.
