Dirac equation for embedded 4-geometries

High Energy Physics - Theory 2013-03-26 v3 General Relativity and Quantum Cosmology

Abstract

We apply Dirac's square root idea to constraints for embedded 4-geometries swept by a 3-dimensional membrane. The resulting Dirac-like equation is then analyzed for general coordinates as well as for the case of a Friedmann-Robertson-Walker metric for spatially closed geometries. The problem of the singularity formation at quantum level is addressed.
