String-inspired Gauss-Bonnet Gravity Inflation and ACT
S. D. Odintsov, V. K. Oikonomou, Pyotr Tsyba +2
In this article we present a systematic observational verification of the ghost-free string-inspired model, where the Gauss-Bonnet invariant is non-minimally cou…

Exact solution of the Einstein-scalar-Gauss-Bonnet model with Noether symmetry constraints
Olga Razina, Dauren Rakhatov, Pyotr Tsyba +1
By applying Noether symmetry methods, analytic solutions are obtained for a generalized Einstein-scalar-Gauss-Bonnet model with a component. Variation with respect to…

Rescaled Einstein-Gauss-Bonnet Gravity Inflation
V. K. Oikonomou, Ardit Gkioni, Iason Sdranis +2
We study the inflationary phenomenology of a rescaled Einstein-Gauss-Bonnet gravity. In this framework, the gravitational constant of the Einstein-Hilbert term is rescaled due to e…
