2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/109859In this short review of Doubly Special Relativity I describe first the relations between DSR and (quantum) gravity. Then I show how, in the case of a field theory with curved momentum space, the Hopf algebra of symmetries naturally emerges. I conclude with some remarks concerning DSR phenomenology and description of open problems.Submitted to the volume "Approaches to Quantum Gravity - toward a new understanding of space, time, and matter", D.
