The phase portrait is represented in a Mercator map and on a 3D sphere. Pitchfork bifurcations and degeneracies (a dense set of equilibria) are found. 000131631 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000131631 590__ $$a1.495$$b2013 000131631 591__ $$aMECHANICS$$b54 / 139 = 0.388$$c2013$$dQ2$$eT2 000131631 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000131631 700__ $$0(orcid)0000-0002-7620-4523$$aCasanova,D.$$uUniversidad de Zaragoza 000131631 700__ $$0(orcid)0000-0001-5208-4494$$aElipe,A.$$uUniversidad de Zaragoza 000131631 700__ $$0(orcid)0000-0002-1374-4645$$aPalacios,M.$$uUniversidad de Zaragoza 000131631 7102_ $$12005$$2595$$aUniversidad de Zaragoza$$bDpto.
