No slow-roll inflation à la Generalized Chaplygin Gas in General Relativity

Alexander Gallego Cadavid, J. R. Villanueva

The Generalized Chaplygin Gas (GCG) model is characterized by the equation of state $P=-A{\rho }^{-\alpha }$, where $A>0$ and $\alpha <1$. The model has been extensively studied due to its inter…
