In this note, we consider the kinetic derivative nonlinear Schrödinger equation (KDNLS), which arises as a model of propagation of a plasma taking the effect of the resonant interaction between the wave modulation and the ions into account. In contrast to the standard derivative NLS equation, KDNLS does not conserve the mass and the energy. Nevertheless, the dissipative structure of KDNLS enables us to show an a priori bound in the energy space and a lower bound of theL2norm for its solution, as we see in this note. Combined with the local wellposedness result, which we plan to show in a forthcoming paper, these bounds will give a global existence result in the energy space for small initial data.
