Generalized Dirac operators on Lorentzian manifolds and propagation of singularities

Published 7 Oct 2011 in math.DG, math-ph, math.AP, and math.MP | (1110.1475v1)

Abstract: We survey the correct definition of a generalized Dirac operator on a Space--Time and the classical result about propagation of singularities. This says that light travels along light--like geodesics. Finally we show this is also true for generalized Dirac operators.
