Warm Inflation

Abstract

Assuming a first order phase transition during inflation, a model scenario is described which does not require a tiny coupling constant. Thermal equilibrium is closely maintained as inflation commences. No large scale reheating is necessary. Solutions for $N>70$ are found for any $\delta \rho /\rho$ in the range $10^{-5}-10^{-3}$.
