Applications of conformal SU(2,2) transformations to spinfoams and spin-networks
Abstract: We construct the the cotangent bundle of SU(2,2) as a symplectic manifold and study different applications of it to spinfoam models and spin-networks. Most notably, the concept of a particle in a Poincaré invariant spacetime is discussed. Additionally, the geometrical interpretation of the full SU(2,2) phase-space in a possible spinfoam context is clarified. The talk will include a brief introduction to spinfoam models and especially a short review of how to include fermions into spinfoams.
