β¦ Synopsis
A phase-field system with memory characterized by a heat conduction law of GurtinPipkin type is considered. This model has been already studied by several authors who have obtained various well-posedness results. The longterm behavior of a single solution has also been investigated. In this note we first formulate the model as a dynamical system in a suitable phase space which accounts for the whole past history of the temperature. Then we prove the existence of a (uniform) absorbing set which basically shows the dissipative nature of the system. Existence of a compact attractor is discussed as well.

## Abstract In this article, we study the long time behavior of a parabolicβhyperbolic system arising from the theory of phase transitions. This system consists of a parabolic equation governing the (relative) temperature which is nonlinearly coupled with a weakly damped semilinear hyperbolic equat
