Generalized variational principles for ion acoustic plasma waves by He’s semi-inverse method. (English) Zbl 1135.76597

Summary: Some generalized variational principles are obtained for ion-acoustic plasma waves by He’s semi-inverse method. The obtained variational principle has profound implications in physical understandings, explaining the interaction between various variables in an energy view and the existence of conservation law.
