| Research Abstract |
The set SL(m) of m-string links has a monoid structure, given by the stacking product. When considered up to concordance, SL(m) becomes a group, which is known to be abelian only if m=1. In this study, we consider a new equivalence relation which endows SL(m) with a group structure, namely the Cn-concordance, which is generated by C_n-equivalence, which is introduced by Habiro, and concordance. We give a necessary and sufficient condition for a pair (m,n) that the Cn-concordant group of m-string links is abelian.
