Critical gravity from four dimensional scale invariant gravity
Abstract We show that a critical condition exists in four dimensional scale invariant gravity given by the pure quadratic action 𝛽 C μvσρ C μνσρ + 𝛼 R 2 where C νσρ μ $$ {C}_{\nu \sigma \rho}^{\mu } $$ is the Weyl tensor, R is the Ricci scalar and 𝛽 and 𝛼 are dimensionless parameters. The critical c...
