Hi, I was wondering if there was anyone who would have a good set of lecture notes online concerning the following problem Basically, what im looking for is the construction of the classical lagrangian of general relativity + classical Yang Mills fields using differential geometry, bundles, guage connections etc. But not really. I am really more interested in the way to go from the classical theory to the quantum field one, using this language. I am trying to stay away from the Palatini formalism, where they abstract away from the Einstein Hilbert action and use SO(3,1) as the connection variable. I'm tired of translating the usual way we are taught quantum field theory, into this language, and I need a good review set of notes that isn't scattered around in various tomes. Any help or suggestions would be greatly appreciated.
