Relative locality at the Planck scale

Dr. Giacomo Rosati

In this seminar I introduce the possibility for the notion of absolutness of locality to be relaxed at the Planck scale, the scale at which quantum gravity effects are supposed to be relevant. Several approaches to quantum gravity suggest that, at such scale, spacetime should exhibit some nontrivial structure, and that relativistic symmetries should be modified. Relativity of locality is a general feature for theories with deformed relativistic symmetries, in which the scale of deformation (the Planck scale) plays the role of a relativistic invariant, and no preferred frame exists.
