Deformed kinematics and Planck scale modifications of Special Relativity — •Lukas Brunkhorst — ZARM, Universität Bremen

In the absence of gravitational fields, Special Relativity provides a well-tested framework for the description of classical point particle motion. And in fact, as will be shown, algebraic analysis reveals as well that there are not many plausible ways to depart from the Poincaré Lie group of spacetime automorphisms. Entering the category of Hopf algebra, the Kappa-Poincaré algebra then forms the attempt to include quantum gravitational effects. I will present its geometrical nature and discuss the derived notion of spacetime, as well as address the occurence of non-quadratic mass shell conditions.
