Connected Floer homology of covering involutions

Abstract:

We use the covering involution of double branched covers of knots to define a knot invariant inspired by connected Heegaard Floer homology. Using this, we obtain novel concordance results.

This is joint work with Antonio Alfieri and Sungkyung Kang.
