The genus filtration in the smooth concordance group
arXiv:1506.02406 · doi:10.2140/pjm.2016.285.501
Abstract
We define a filtration of the smooth concordance group based on the genus of representative knots. We use the Heegaard Floer epsilon and Upsilon invariants to prove the quotient groups with respect to this filtration are infinitely generated. Results are applied to three infinite families of topologically slice knots.
