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.
Keywords : Global solution, global attractor, long-time behavior of solutions, semilinear degenerate hyperbolic equation, unbounded domains, gradient systems, tail-estimates method
