We present a derivation of a generic relativistic isotropic deformed kinematics and discuss the complementarity and relations with other derivations based on kappa-Poincare Hopf algebra or on the geometry of a maximally symmetric momentum space.2020http://zaguan.unizar.es/record/8926910.1103/PhysRevD.101.044057http://zaguan.unizar.es/record/89269oai:zaguan.unizar.es:89269info:eu-repo/grantAgreement/EUR/COST-Action/CA18108info:eu-repo/grantAgreement/ES/DGIID-DGA/2015-E24-2info:eu-repo/grantAgreement/ES/MINECO-FEDER/PGC2018-095328-B-I00Physical Review D 101, 4 (2020), 044057 [15 pp.]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
