Hilbert invariant integral
WebAug 9, 2024 · Not sure why you want to restrict our self to a one-parameter group of diffeos, this action is clearly invariant under a finite diffeomorphism because it is the integral of a 4-form R − g d x 0 ∧... ∧ d x 3 and we know that integrals of 4-forms are invariants (on a 4 dimensional manifold that is).
