链接quandles是剩余有限的

Link quandles are residually finite

Valeriy G. Bardakov, Mahender Singh, Manpreet Singh

摘要:

剩余有限性是组合群论和低维拓扑学中的一个重要性质。在最近的工作[2]中,引入了quandles的剩余有限性,并证明了自由quandles和纽结quandles是剩余有限的。本文推广了这些结果,证明了剩余有限quandle的自由积是剩余有限的,只要它们的相伴群是剩余有限的。由于链接quandle的关联群是链接群,已知其是剩余有限的,因此链接quandle是剩余有限的。

英文摘要:

Residual finiteness is known to be an important property of groups appearing in combinatorial group theory and low dimensional topology. In a recent work [2] residual finiteness of quandles was introduced, and it was proved that free quandles and knot quandles are residually finite. In this paper, we extend these results and prove that free products of residually finite quandles are residually finite provided their associated groups are residually finite. As associated groups of link quandles are link groups, which are known to be residually finite, it follows that link quandles are residually finite.
