Abstract:
A certain class of reaction-diffusion systems with feedback effect subject to homogeneous Neumann boundary condition and the positive steady-state solutions are considered. Some priori estimates are established for positive steady-state solutions, then the effects of the diffusion coefficient on the nonexistence of positive non-constant steady-state solutions are analyzed by the energy method and implicit functional theorem. The results show that if one of the coefficients is large enough, the system has no positive non-constant steady-state solutions.
Key words: reaction-diffusion system; positive steady-state solutions; non-existence
