Existence of Solutions for a Quasilinear Reaction Diffusion System

الملخص EN

The degenerate reaction diffusion system has been applied to a variety of physical and engineering problems.

This paper is extended the existence of solutions from the quasimonotone reaction functions (e.g., inhibitor-inhibitor mechanism) to the mixed quasimonotone reaction functions (e.g., activator-inhibitor mechanism).

By Schauder fixed point theorem, it is shown that the system admits at least one positive solution if there exist a coupled of upper and lower solutions.

This result is applied to a Lotka-Volterra predator-prey model.
