Thanks for all your advice, which collectively has resolved my problem. I hope that soon I’ll be able to say I understand LQG! Marcus, thanks for the welcome! I agree with you that the classical approach is the best place to start. Those lectures are a useful tool thank you, when I find the...

I am currently studying loop quantum gravity, and therefore GR in Ashtekar variables (A,E). I see the vector constraint E^a_iF^i_{ab}=0 is said to generate spatial diffeomorphisms (where F is the Yang-Mills field strength in terms of A), but how can I show this? How do spatial diffeomorphisms...
