WebAug 9, 2024 · We parametrize the model with some parameters/couplings (guess and hope its right), then integrate over all "diffeomorphism invariant configurations", because several "seemingly different" configurations are actually related to the same physical situation, and not normalising properly would ruin the idea behind the path integral formalism.

If I take the wave equation ψ = 0 for example, this is not diff. invariant because it really means η μ ν ∇ μ ∇ ν ψ = 0, and if I apply a diffeo ϕ, it messes up η μ ν, which is part of the background. In other words, the wave equation is not "solving for" η μ ν. However with Einstein's equations, all the ...
