Abstract
We consider the damped inhomogeneous and anisotropic elastic wave
equation with a memory on bounded domain. We apply the Morawetz
estimates and the compactness-uniqueness arguments to prove the
stability results. We also give a discussion of the instability of the
system when the proposed condition is not satisfied.
