Locality of interactions is the principle which defines the spacetime structure for a system of particles. The formulation based on kappa-Poincare Hopf algebra is shown to be contained in this framework as a particular example.2018http://zaguan.unizar.es/record/7023810.1103/PhysRevD.97.064025http://zaguan.unizar.es/record/70238oai:zaguan.unizar.es:70238info:eu-repo/grantAgreement/ES/DGA/E24-2info:eu-repo/grantAgreement/ES/MINECO/FPA2015-65745-PPHYSICAL REVIEW D 97, 6 (2018), 064025 [12 pp]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
