Journal of Knot Theory and Its Ramifications, 25 (12), 1642015-1-1642015-14.0218-21651793-6527http://hdl.handle.net/11441/49206Strongly quasipositive links are those links which can be seen as closures of positive braids in terms of band generators. In this paper we give a necessary condition for a link with braid index 3 to be strongly quasipositive, by proving that in that case it has positive Conway polynomial (that is, all its coefficients are non-negative). We also show that this result cannot be extended to a higher number of strands, as we provide a strongly quasipositive braid whose closure has non-positive Conway polynomial.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/BraidsConway polynomialPositive linksStrongly quasipositive linksStrongly quasipositive links with braid index 3 have positive Conway polynomialinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1142/S0218216516420153https://idus.us.es/xmlui/handle/11441/49206
