On a nonolinear wave equation in unbounded domains

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
We study existence and uniqeness of the nonlinear wave equation∂2u∂t2+M(x,∫|∇u(x,t)|2dx+∫|u(x,t)|2dx)(−Δu+u)=0in unbounded domains. The above model describes nonlinear wave phenomenon in non-homogeneous media.
