摘要：In this talk, we consider the nonlinear wave equation in inhomogeneous media, which is modeled by the variable coefficient wave equation. By taking the periodic solutions as a breakthrough, we study the dynamical complexity of its solutions and the essentially different dynamical behaviors for the spatially inhomogeneous wave equation.
