Homotopy ribbon concordance, Blanchfield pairings, and twisted Alexander polynomials
Published online by Cambridge University Press: 12 April 2021
Abstract
We establish homotopy ribbon concordance obstructions coming from the Blanchfield form and Levine–Tristram signatures. Then, as an application of twisted Alexander polynomials, we show that for every knot K with nontrivial Alexander polynomial, there exists an infinite family of knots that are all concordant to K and have the same Blanchfield form as K, such that no pair of knots in that family is homotopy ribbon concordant.
