|Title||Invariants for handlebody-knots derived from Yetter--Drinfeld modules|
A handlebody-knot is a handlebody embedded in the 3-sphere. Two handlebody-knots are equivalent if one can be transformed into the other by an isotopy of the 3-spere. We introduce invariants for handlebody-knots derived from Yetter--Drinfeld modules. This is a joint work with Akira Masuoka.
