Stabilization of Starobinsky-Vilenkin stochastic inflation by an environmental noise

12 Feb 2019 Haba Z.

We discuss the inflaton $\phi$ in an interaction with an infinite number of fields treated as an environment (noise) with a friction $\gamma^{2}>0$. In a Markovian approximation we obtain a stochastic wave equation (appearing also in the warm inflation models)... (read more)
