Quandles at Finite Temperatures III

Joaquim Bojarczuk | Lopes, Pedro

Keywords: Quandles | colorings | 2-dimensional braids | ribbon knots | 2-twist-spun knots

We resume work on telling embeddings of codimension two apart by counting colorings of the corresponding diagrams by given quandles. Previously, we illustrated the efficiency of this approach on classical knots. In the present paper we apply it to knotted surfaces. We recover work of Kamada in telling ribbon knots apart and we distinguish all elements of a class of twist-spun torus knots.
