We study the cosmological model based on Einstein-Gauss-Bonnet gravity with non-minimal coupling of a scalar field to a Gauss-Bonnet term in 4D Friedmann universe. We show how constructing the exact solutions by the method based on a confrontation of the Hubble parameter in the model under consideration with that in a standard scalar field inflationary cosmology.

  1. Einstein--Gauss--Bonnet Inflationary Cosmology in Phase-$\theta$ Formalism

    gr-qc 2026-07 conditional novelty 5.0 of 10

    Phase-θ formalism maps EGB inflation backgrounds to closed-form observables beyond slow-roll; Starobinsky+linear-GB fits ACT DR6 ns and r while predicting a DECIGO-accessible GW plateau.

  2. Autonomous Dynamical System of Einstein-Gauss-Bonnet Cosmologies

    gr-qc 2019-08 conditional novelty 4.0 of 10

    A phase space analysis of Einstein-Gauss-Bonnet cosmology finds a stable equilibrium and a heteroclinic orbit, but the equilibrium requires the Gauss-Bonnet coupling to vanish and the orbit violates the Friedmann constraint.
