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, $V(\varphi )\propto {\varphi }^2$, we develop a model where the dissipation coefficient $\Gamma ={\Gamma }_0=$ constant. We use recent astronomical observations for constraining the parameters appearing in our model.
