Basic properties of these invariants are presented, and the triple-point spectra of S2 × S1 and S3 are computed.2019http://zaguan.unizar.es/record/13138910.1007/s00009-019-1340-zhttp://zaguan.unizar.es/record/131389oai:zaguan.unizar.es:131389info:eu-repo/grantAgreement/ES/DGA/E22-20Rinfo:eu-repo/grantAgreement/ES/MINECO/MTM2013-45710-C2-1-Pinfo:eu-repo/grantAgreement/ES/MINECO/MTM2013-46337-C2-2-Pinfo:eu-repo/grantAgreement/ES/MINECO/MTM2016-76868-C2-2-Pinfo:eu-repo/grantAgreement/ES/MINECO/MTM2016-77642-C2-2-PMediterranean Journal of Mathematics 16, 3 (2019), 71 [19 pp.]All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
