New scenario of decay rate for system of three nonlinear wave equations with visco-elasticities
A system of three semilinear wave equations with strong external forces in $ \mathbb{R}^n $ is considered. We use weighted phase spaces, where the problem is well defined, to compensate the lack of Poincare's inequality. Using the Faedo-Galerkin method and some energy estimates, we prove the ex...
