Detecting fibered strongly quasi-positive links

Abstract

We prove that an nn-component fibered link LL in S3S^3 is strongly quasi-positive if and only if τ(L)=g3(L)+n1\tau(L)=g_3(L)+n-1, where g3(L)g_3(L) denotes the Seifert genus and τ\tau is the Ozsv\'ath-Szab\'o concordance invariant. We also provide a table which contains a list of some fibered prime links with at most 9 crossings; and we explicitly determine the ones that are strongly quasi-positive and their maximal self-linking number.
