【 摘 要 】

During the last decade, there have been relevant advances in the study of quantum gravity coupled to point particles in 2+1 dimensions. In the emerging picture the momentum space of the particles is curved, the spacetime coordinates are noncommuting and the symmetries are DSR-deformed relativistic symmetries. In this article we study some phenomenological consequences of these features via the so- called ''relative-locality" framework. We find that a ''dual-gravity" lensing effect appears as a consequence of the relativity of spacetime locality associated to the deformed symmetries of the theory.
