As a consequence, a simple proof solving a question posed by Papadima on the characterization of algebraic links that have quasi-projective fundamental groups is provided. The type of quasi-projective obstructions used here are in the spirit of Papadima’s original work. info:eu-repo/grantAgreement/ES/DGA/FMI53-10 info:eu-repo/grantAgreement/ES/MICINN/MTM2016-76868-C2-2-P info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 0.631 2020 Mathematics (miscellaneous) 2020 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Cogolludo-Agustín, José Ignacio Universidad de Zaragoza (orcid)0000-0003-1820-6755 Matei, Daniel 2006 440 Universidad de Zaragoza Dpto.
