Warm inflationary model in loop quantum cosmology

Abstract

A warm inflationary universe model in loop quantum cosmology is studied. In general we discuss the condition of inflation in this framework. By using a chaotic potential, $V(\ensuremath{\phi})\ensuremath{\propto}{\ensuremath{\phi}}^{2}$, we develop a model where the dissipation coefficient $\ensuremath{\Gamma}={\ensuremath{\Gamma}}_{0}=\mathrm{\text{constant}}$. We use recent astronomical observations for constraining the parameters appearing in our model.
