Canonical gravity with free characteristic data
Speaker:Dr. Michael Reisenberger (Inst. de Fisica, Facultad de Ciencias, Montevideo, Uruguay) (Fakultät für Physik)
Abstract:Abstract: Free (unconstrained) initial data for general relativity on a pair of intersecting null hypersurfaces are well known, but the lack of a Poisson bracket and concerns about caustics have stymied the development of a constraint free canonical theory. I describe how caustics and generator crossings can be neatly avoided and a Poisson bracket on free data is presented. This work is part of an effort to understand the holographic principle of “t Hooft".
