In this study, the scenario of a two-component warm tachyon inflation is considered, where
the tachyon field plays the role of the inflaton by driving the inflation. During inflation, the …

The scenario of constant-roll inflation in the frame of the Randall-Sundraum II (RS II) brane
gravity model is considered. Based on the scenario, the smallness of the second slow-roll …

Systematic understanding for classes of inflationary models is investigated from the
viewpoint of the local conformal symmetry and the slightly broken global symmetry in the …

The beta-function formalism is being used to study the constant-roll inflation in k-essence
models. Assuming the second slow-roll parameter as a constant leads to a first-order …

The constraint of trans-Planckian censorship conjecture on the brane inflation model is
considered. The conjectures put an upper bound on the main parameter including …

In this paper we consider the α− attractor model and study inflation under a non-slow-roll
dynamics. More precisely, we follow the approach recently proposed by Gong and Sasaki [1] …

Within the framework of tachyon inflation, we consider different steep potentials and check
their viability in light of the Planck 2015 data. We see that in this scenario, the inverse power …

The slow-roll inflation scenario is studied in the frame of the scalar–tensor theory of gravity,
where the scalar field has a nonminimal coupling to the geometric part. After deriving the …

We consider inflation in a five-dimensional space time with the inflaton field confined to live
on a brane world. In this scenario, we study different types of potentials for the inflaton …

We revisit inflation with non-canonical scalar fields by applying deformed-steepness
exponential potentials. We show that the resulting scenario can lead to inflationary …
