Einstein Gauss-Bonnet theories as ordinary, Wess-Zumino conformal anomaly actions
Recently, the possibility of evading Lovelock's theorem at d=4, via a singular redefinition of the dimensionless coupling of the Gauss-Bonnet term, has been very extensively discussed in the cosmological context. The term is added as a quadratic contribution of the curvature tensor to the Einst...
