A note on applications of the dd-invariant and Donaldson's theorem

    https://doi.org/10.1142/S0218216517400065Cited by:1 (Source: Crossref)

    This paper contains two remarks about the application of the dd-invariant in Heegaard Floer homology and Donaldson's diagonalization theorem to knot theory. The first is the equivalence of two obstructions they give to a 2-bridge knot being smoothly slice. The second carries out a suggestion by Stefan Friedl to replace the use of Heegaard Floer homology by Donaldson's theorem in the proof of the main result of [J. E. Greene, Lattices, graphs, and Conway mutation, Invent. Math.192(3) (2013) 717–750] concerning Conway mutation of alternating links.
