列组及其链接不变量

The column group and its link invariants

Johanna Hennig, Sam Nelson

摘要:

列群是由birack矩阵中的列置换生成的有限黑板birack的元素上的对称群的子群。我们使用子群的列群相关联的birack同态定义的积分birack计数不变量的增强,并给出的例子表明,增强的不变量是强于未增强的不变量。

英文摘要:

The column group is a subgroup of the symmetric group on the elements of a finite blackboard birack generated by the column permutations in the birack matrix. We use subgroups of the column group associated to birack homomorphisms to define an enhancement of the integral birack counting invariant and give examples which show that the enhanced invariant is stronger than the unenhanced invariant.
