Warm inflationary model in the context of loop quantum cosmology is investigated. To this aim we consider two cases intermediate inflation and logamediate inflation. In both the cases, assuming a constant dissipation coefficient, we study the model under consideration in weak dissipation regime and also in strong dissipation regime. In each of these cases, we obtain various parameters such as potential function of inflationary scalar field and slow-roll parameters. Perturbation theory and also finding relations between perturbative parameters is studied.

In this note, Logamediate inflationary model on the brain by using canonical scalar fields is studied. The equation of motion is calculated in the slow-roll approximation for canonical model. Perturbation parameters of the model are presented and constrained by the Planck observational data. The results are compatible with the observations.
