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.2013http://zaguan.unizar.es/record/13163110.1016/j.mechrescom.2012.12.005http://zaguan.unizar.es/record/131631oai:zaguan.unizar.es:131631MECHANICS RESEARCH COMMUNICATIONS 48 (2013), 59-65by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
