Abstract: The aim of this paper is to prove the existence of periodic maximal and minimal solutions for a class of degenerate parabolic reaction diffusion models, including the uniqueness of the positive solution. To answer these questions, we use a technique described by Pao based on the method of upper and lower solutions, its associated monotone interactions and various comparison principles.
