The Geometry of relative locality

Laurent Freidel

Perimeter Institute

In this talk I will review some of the general motivation behind relative locality which is an extension of the relativity principle. I will show how this leads at the classical level to a new concept of geometry, the Born geometry which allows the differential structure to be itself dynamical. How it leads at the quantum level to a new concept of space: Modular space and exemplify how it affect the effective geometry of string theory. And what new action principle it leads to.
