Analytical calculation of the observational parameters for tachyon inflation
Marko Stojanovic, Neven BiliÄ, Goran S. Djordjevic +2
We investigate the possibility of analytically calculating observational parameters in tachyon inflation cosmology, using the Hubble expansion rate as a function of the tachyon fie…

A scaling invariance of the perturbations in -inflation models
Neven BiliÄ, Dragoljub D. DimitrijeviÄ, Goran S. Djordjevic +2
We study the background and perturbations in -essence inflation models and show that a general -essence exhibits a simple scaling property. In particular, we study two classe…
