A twisted torus link T(p,q,r,s) is obtained by performing s full twists on r adjacent strands of the (p,q)-torus link. In this talk, we classify twisted torus links that are unlinks. We give a complete characterization of all parameter families (p,q,r,s) for which the associated twisted torus link is an unlink. This is a joint work with Thiago de Paiva and 蓝青.
