Abstract
I will report on joint work with Jonathan Simone in which we show that an appropriate generalisation of the slice–ribbon conjecture to links holds in the case of non-alternating quasi-alternating 3-braid closures. The proof employs a marriage of tools from Heegaard Floer theory and lattice calculus, as well as a nontrivial computational component.
