General Expressions for and for Several Minimally Coupled Single Scalar Field Models
Marko Stojanovic, Dragoljub D. Dimitrijevic, Milan Milosevic
We derive a generalized expressions for the scalar power spectrum and the observational parameters of inflation (the scalar spectral index and the tensor-to-scalar rati…

Constant-roll inflation with tachyon field in the holographic braneworld
Marko Stojanovic, Neven Bilic, Dragoljub D. Dimitrijevic +2
We study inflation driven by the tachyon field in the holographic braneworld by assuming the second slow-roll parameter is constant. The parameter can be either defined b…

On attractor behavior in braneworld constant-roll inflation
Goran S. Djordjevic, Neven BiliÄ, Dragoljub D. Dimitrijevic +2
We investigate in detail the attractor behavior of some inflationary models based on braneworld dynamics under the constant-roll condition. We describe the dynamics of the models,…
