Abstract
We introduce a new class of links for which we give a lower bound for the slice genus g∗, using the generalized Rasmussen invariant. We show that this bound, in some cases, allows one to compute g∗ exactly; in particular, we compute g∗ for torus links. We also study another link invariant: the strong slice genus g∗. Studying the behaviour of a specific type of cobordisms in Lee homology, a lower bound for g∗ is also given.
