Deformed relativistic symmetries : decoherence and dimensional reduction at the Planck scale

Michele Arzano (Roma, La Sapienza)

I will start with a brief introduction to the framework of deformed relativistic symmetries based on Lie-group momentum spaces whose curvature sets a fundamental (Planckian) UV scale at the kinematical level. I will then show how these models can be related to a fundamental decoherence at the Planck scale and how they are relevant for the phenomenon of “dimensional reduction”, ubiquitous in a variety of approaches to quantum gravity.
