Using semigroups theory, regularity results and a theorem associated
to the Lumer Phillips theorem, we prove the existence of global
solution for a coupled wave system. Also, using multiplicative
techniques and the classic Gearhart theorem, introduced in Liu-Zheng
[7], we prove that energy associated to the system decays
exponentially to zero when 
Here we give two new and interesting
proofs.
Stability for a coupled wave system has been considered in [13], where
they used Prüs result [12].
