Abstract

We prove that for particular infinite families of LL-spaces, arising as branched double covers, the dd-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 Δ5\Delta \geq 5, the existence of infinitely many non-quasi-alternating homologically thin knots with determinant Δ2\Delta^2, and a result by Hoffman and Walsh concerning the existence of hyperbolic weight 11 manifolds that are not surgery on a knot in S3S^3.
