| Abstrakt: | We prove that the group C∼$\widetilde{\mathcal {C}}$ of equivariant concordance of directed strongly invertible knots, defined by Sakuma (On strongly invertible knots, Algebraic and topological theories (Kinosaki, 1984), Kinokuniya Company Ltd., Tokyo, 1986, pp. 176–196), is not abelian. We do so by exhibiting an infinite family of non‐trivial commutators. [ABSTRACT FROM AUTHOR] |
