Abstract : The aim of this paper is to prove the existence of the global attractor of
the Cauchy problem for a semilinear degenerate hyperbolic equation involving strongly
degenerate elliptic differential operators.
The attractor is characterized as the unstable manifold of the set of stationary points, due to the
existence of a Lyapunov functional.
