Late time acceleration in $$f(G)$$ model

Abstract

Late time transition is obtained with a function of Gauss Bonnet curvature \(f(G)\) in the Einstein Hilbert action with a matter field in a FLRW spacetime assuming an ansatz without a specific \(f(G)\). Late time accelerating expansion is either a phantom era without Big Rip singularity or a quintessence era or a de-Sitter era of expansion. The equation of state parameter, jerk and snap parameters support observational data and the function \(f(G)\) obtained from the solution supports earlier works.
