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 [Formula: see text]. Studying the behavior of a specific type of cobordisms in Lee homology, a lower bound for [Formula: see text] is also given.
