We consider inflation in a five -dimensional space time with the inflaton field confined to live on brane world. In this scenario, we study different types of potentials for inflaton, discuss their observational consequences, and compare data. find that some class are good agreement observation value can be sub-Planckian. Moreover, investigate swampland criteria scenario determine consistency m...

Swampland conjectures have attracted quite some interest in the cosmological community. They been shown to wide ranging implications, like constraints on inflationary models, primordial black holes, dark energy name a few. Particularly, their implications single-field models general relativity-based cosmology gathered huge attention. usual form be incompatible with these kinds of or induce seve...

We argue that dS vacua in the LARGE-volume scenario of type IIB string theory are vulnerable to various unsuppressed curvature, warping and gs corrections. work out general how these corrections affect moduli vevs, vacuum energy masses 4D EFT for two Kähler moduli, conifold modulus a nilpotent superfield describing anti-brane uplift. Our analysis reveals parametrically larger relevant expressio...

In this paper, we study the inflationary scenario in realm of k-essence model and swampland conjectures. Taking into account three models Chaplygin gas, such as generalized, modified, generalized cosmic gas models, discuss equation state (EoS) parameter ω, slow roll parameters (ϵ(ϕ),η(ϕ)), curvature perturbation (Ps), tensor to scalar ratio (r), spectral index (ns). As regards model, coupling f...
