Abstract

We provide new information about the structure of the abelian group of topological concordance classes of knots in . One consequence is that there is a subgroup of infinite rank consisting entirely of knots with vanishing Casson–Gordon invariants but whose non-triviality is detected by von Neumann signatures.
