Global Existence And Growth Of Solutions To Coupled Degeneratly Damped Klein-Gordon Equations, Fatma Ekinci, Erhan Pişkin
Al-Qadisiyah Journal of Pure Science
We study a system of nonlinear Klein-Gordon equations with viscoelastic and degenerate damping in a bounded domain. We prove the global existence and exponential growth of solutions with negative initial energy.
