Abstract
We study the Cauchy problem for the nonlinear wave equation with nonli near damping au(t)\u(t)\(m-1) and a nonlinear source term of type bu\u \(p-1). When 1 < p less than or equal to m, a global existence result is established for any initial data. When 1 < m < p, a finite time blo w-up result is proved for compactly supported data with negative initi al energy.
