Abstract: In this talk we consider the focusing radial Klein-Gordon equation with positive damping in the whole space  R^n. We first recall the basic properties of the Klein-Gordon equation and write it as a dynamical system. Then, using dynamical systems tools and different functionals,  we state that each global (in positive time) orbit converges to an equilibrium point as the positive time t goes to infinity.
