    On d-invariants and generalized Kanenobu knots

    We prove that for particular infinite families of L-spaces, arising as branched double covers, the d-invariants defined by Ozsváth and Szabó assume arbitrarily large positive and negative values. As a consequence, we generalize a result by Greene and Watson by proving, for every odd number Δ5, the existence of infinitely many non-quasi-alternating homologically thin knots with determinant Δ2, and a result by Hoffman and Walsh concerning the existence of hyperbolic weight 1 manifolds, that are not surgery on a knot in S3.
