Wb. Fitzgibbon et al., STABILITY AND LYAPUNOV FUNCTIONS FOR REACTION-DIFFUSION SYSTEMS, SIAM journal on mathematical analysis, 28(3), 1997, pp. 595-610
It is shown for a large class of reaction-diffusion systems with Neuma
nn boundary conditions that in the presence of a separable Lyapunov st
ructure, the existence of an a priori L-tau estimate, uniform in time,
for some tau > 0, implies the L-infinity-uniform stability of steady
states. The results are applied to a general class of Lotka-Volterra s
ystems and are seen to provide a partial answer to the global existenc
e question for a large class of balanced systems with nonlinearities t
hat are not bounded by any polynomial.
