Inflation with a quartic potential in the framework of
  Einstein-Gauss-Bonnet gravity
  We investigate inflationary dynamics in the framework of the
Einstein-Gauss-Bonnet gravity. In the model under consideration, the inflaton
field is non-minimally coupled to the Gauss-Bonnet curvature invariant, so that
the latter appears to be dynamically important. We consider a quartic potential
for the inflaton field, in particular the one asymptotically connected to the
Higgs inflation, and a wider class of coupling functions not considered in the
earlier work. Keeping in mind the observational bounds on the parameters - the
amplitude of scalar perturbations $A_s$, spectral index $n_s$ and
tensor-to-scalar ratio $r$, we demonstrate that the model a quartic potential
and the proposed coupling function is in agreement with observation.
