Abstract

We consider the plasma heating nonlinearities that are important in many wave-interaction processes. By means of some simple examples, we analyse the nonlinear terms originating from the collision integral for a weakly collisional plasma. As a result, it turns out to be necessary to generalize the collisional Zakharov equations by including the contribution from the non-diagonal part of the pressure tensor. A new system of equations is thus presented.
