Generalization of cosmological attractor approach to Einstein-Gauss-Bonnet gravity

Understand

We construct models with the Gauss-Bonnet term multiplied to a function of the scalar field leading to inflationary scenario.

• The consideration is related with the slow-roll approximation.
• The cosmological attractor approach gives the spectral index of scalar perturbations which is in a good agreement with modern observation and allows variability for tensor-to-scalar ratio.
• We reconstruct models with variability of parameters which allow to reproduce cosmological attractor predictions for inflationary parameters in the leading order of $1/N$ approximation in the Einstein-Gauss-Bonnet gravity.
