Abstract
In this article, equations of thermoelasticity of type III in three-dimensional cylindrical domain are studied. We prove a Phragmén–Lindelöf alternative result, i.e. the smooth solutions either grow or decay exponentially as the distance from the entry section tends to infinity. In the decay case, the authors indicate how to bound explicitly the total energy in terms of data. The continuous dependence of the solutions on the coefficient ρ is also proved in this article.
