Slow-roll approximations for Gauss-Bonnet inflation revisited
Bogdan A. Rudenko, Maria A. Skugoreva, Alexey V. Toporensky
In our paper we consider the validity of slow-roll approximations for Gauss-Bonnet inflation introduced in [1]. In contrast to the cited paper where the coupling function before th…

More accurate slow-roll approximations for inflation in scalar-tensor theories
Ekaterina O. Pozdeeva, Maria A. Skugoreva, Alexey V. Toporensky +1
We propose new versions of the slow-roll approximation for inflationary models with nonminimally coupled scalar fields. We derive more precise expressions for the standard slow-rol…

Emergence of cosmological scaling behavior in asymptotic regime
M. A. Skugoreva, M. Sami, N. Jaman
In this paper we consider a scalar field system with a class of potentials given by the expression, ; for which $…
