G. Izus et al., GLOBAL STABILITY OF STATIONARY PATTERNS IN BISTABLE REACTION-DIFFUSION SYSTEMS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 52(1), 1995, pp. 129-136
We study a piecewise linear version of a one-component, one-dimensiona
l reaction-diffusion bistable model, with the aim of analyzing the eff
ect of boundary conditions on the formation and stability of stationar
y patterns. The analysis proceeds through the study of the behavior of
the Lyapunov functional in terms of a control parameter: the reflecti
vity at the boundary. We show that, in this example, this functional h
as a very simple and direct geometrical interpretation.
