NettetVlasov equation fails to capture nonlinear saturation, which can be important. A possible third approach, immune to these limitations, is to solve numerically the complete Vlasov equation. While direct numerical methods for the Vlasov equations have enjoyed a certain degree of popularity in plasma physics after the seminal paper by Cheng and ... Nettetlinear wave theory in favor of a thoroughly nonlinear theory. In particular, the failure to describe the formation of persistent long-lived structures by a perturbative treatment of the Vlasov equation is highlighted. This is achieved by an extended revision of the theory of stationary coherent waves:
