Description	In the talk I will explain how to obtain lower bounds on unlinking numbers through 4-manifold techniques using a generalization of a theorem of Cochran-Lickorish. The method will be illustrated using links from Kohn's table whose unlinking numbers have only recently been determined through these methods.
