On d-invariants and generalised Kanenobu knots

Abstract

We prove that for particular infinite families of L-spaces, arising as branched double covers, the d-invariants defined by Ozsv\'ath and Szab\'o are arbitrarily large and small. As a consequence, we generalise a result by Greene and Watson by proving, for every odd number ≥ 5, the existence of infinitely many non-quasi-alternating homologically thin knots with determinant 2, and a result by Hoffman and Walsh concerning the existence of hyperbolic weight 1 manifolds that are not surgery on a knot in S3.
