Variational and Conformal Structure of Nonlinear Metric–connection Gravitational Lagrangians

Abstract

According to the standard variational principle (Hilbert variation) that leads to the Einstein field equations of general relativity, the gravitational action ∫ R √−g is varied with respect to the metric tensor of a spacetime manifold that is taken to be a four-dimensional Lorentz manifold (M,g) with metric g and the Levi–Civita connection ∇. However, in… (More)
