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(\ensuremathφ)\ensuremath∝\ensuremathφ², we develop a model where the dissipation coefficient \ensuremathΓ=\ensuremathΓ₀=constant. We use recent astronomical observations for constraining the parameters appearing in our model.
