Аннотация: In 1980s, Joyce and Matveev introduced a quandle which is an algebraic structure related to knot theory. In the papers, they also showed that for given a group and a group automorphism, there is a quandle structure on the group, later called ’generalized Alexander quandle’. In particular, when the automorphism is an inner automorphism by a fixed element Язык доклада: английский |
