Title: The full Zakharov equations in nonextensive q-plasma

The wave-wave interactions among electromagnetic mode, Langmuir and ion-sound modes are theoretically investigated in a nonextensive plasma, with the help of the two-fluid theory and the two-scale method. The full Zakharov equations for the nonextensive distribution are derived and analyzed numerically. The results show that the collapsing of the three waves would be affected by the nonextensive parameter q. When q increasing, the collapsing would become faster and the rate of density perturbation would be greater. And the localized density structure would form a plasma channel much easier.
