|Title||Twisted biquandles and invariants of twisted links|
A biquandle is a set with two binary operations satisfying certain conditions coming from Reidemeister moves. We consider an additional structure related to twisted knots. The number of colorings is an invariant of a twisted knot. There is also a notion of the fundamental twisted biquandle of a twisted knot. This is a joint work with Naoko Kamada.
