Spatial estimates for a system of coupled parabolic-hyperbolic equations under nonlinear boundary condition

The aim of this study is to present spatial estimates of Phragmen-Lindelof type for a dynamical system. We show that an appropriate measure of the solutions either tends to infinity by exponential rate or decays to zero by exponential rate. (c) 2006 The Franklin Institute. Published by Elsevier Ltd.
