| The concordance group of classical knots C was introduced over 50 years ago by Fox and Milnor. It is a much-studied and elusive object which among other things has been a valuable testing ground for various new topological (and smooth 4-dimensional) invariants. In this talk I will address the problem of embedding C in a larger group corresponding to the inclusion of knots in links. | |||
