The exterior calculus of quadratic gravity

Year: 2025

Type: article

Abstract: The metric tensor field equations for the general quadratic curvature gravity in four spacetime dimensions are derived by making use of the algebra of the exterior forms defined on the pseudo-Riemannian manifolds and the identities satisfied by the Riemann curvature tensor. The linearized metric field equations are formulated in terms of the perturbation 1-form fields.
