An inflationary equation-of-state

We have studied inflationary paradigm through an equation of state. With a single parameter state as function the scalar field responsible for accelerated expansion, we find observationally viable model satisfying all constraints laid down by recent observations. The resulting can efficiently cover wide range tensor-to-scalar ratio ranging from $r\sim\mathcal{O}(10^{-1})$ to $\mathcal{O}(10^{-6})$, other observables being consistent with latest data. Nowadays ultimate eliminator between models is ratio, presented here capable keeping up future probes at same time having good agreement observables.
