Power-law Bianchi type I inflation with multiple vector fields
Duy H. Nguyen, Tuan Q. Do
We investigate an inflationary anisotropic universe in a supergravity-motivated model with one scalar field non-minimally coupled to multiple vector fields. We restrict ourselves t…

Stability investigations of de Sitter inflationary solutions in power-law extensions of the Starobinsky model
Tuyen M. Pham, Duy H. Nguyen, Tuan Q. Do +1
In this paper, we would like to examine whether stable de Sitter inflationary solutions appear within power-law extensions of the Starobinsky model. In particular, we will address…
