Links, Milnor's invariants, and robust manifolds
by

Milnor's invariants provide an obstruction for a link to be slice, and more generally to be homotopically trivial. I will discuss an extension of this theory to links bounding disjoint more general, "robust", 4-manifolds in the 4-ball. This problem is motivated by the 4-dimensional topological surgery conjecture.
