Abstract:

Let L be an oriented tame link in the three sphere ${S^3}$. We study the Murasugi signature, $\sigma (L)$, and the nullity, $\eta (L)$. It is shown that $\sigma (L)$ is a locally flat topological concordance invariant and that $\eta (L)$ is a topological concordance invariant (no local flatness assumption here). Known results about the signature are re-proved (in some cases generalized) using branched coverings.
