General relativity as a gauge theory
WebAbout This Book. This invaluable book presents gravitation and gauge fields as interrelated topics with a common physical and mathematical foundation, such as gauge theory of gravitation and other fields, giving emphasis to the physicist's point of view. About half of the material is devoted to Einstein's general relativity theory, and the rest ... Webwhere h = h.As before, we can raise and lower indices using and , since the corrections would be of higher order in the perturbation.In fact, we can think of the linearized version of general relativity (where effects of higher than first order in h are neglected) as describing a theory of a symmetric tensor field h propagating on a flat background spacetime.
