On covariant perturbations with scalar field in modified Gauss–Bonnet gravity

Abstract We investigate cosmological perturbations of f(G) gravity in the presence of a scalar field. Using the $$1+3$$ 1 + 3 covariant formalism, we present the energy overdensity perturbation equations responsible for large scale structure formation. After applying harmonic decomposition method to...
