Instantons, concordance, and Whitehead doubling

Matthew Hedden, Paul Kirk

Published 2010-09-27, updated 2010-10-04Version 2

We use moduli spaces of instantons and Chern-Simons invariants of flat connections to prove that the Whitehead doubles of (2,2^n-1) torus knots are independent in the smooth knot concordance group; that is, they freely generate a subgroup of infinite rank.
