@inproceedings{Venikoudis2021InflationWG, title={Inflation with Gauss–Bonnet and Chern–Simons higher-curvature-corrections in the view of GW170817}, author={S. A. Venikoudis and F P Fronimos}, year={2021} }

Inflationary era of our Universe can be characterized as semi-classical because it can be described in the context of four-dimensional Einstein’s gravity involving quantum corrections. These string motivated corrections originate from quantum theories of gravity such as superstring theories and include higher gravitational terms as, Gauss-Bonnet and Chern-Simons terms. In this paper we investigated inflationary phenomenology coming from a scalar field, with quadratic curvature terms in the view…
