TLDR
In this article, the methode des echelles multiples is used for etablir a non lineaire equation of Schrodinger non-lineaire, which decrit l'evolution non lineaires des ondes lentes du plasma electronique se propageant le long d'une colonne de plasma cylindrique chaud, entoure par un milieu dielectrique and immerge dans un champ magnetique axial infini.Abstract:

TL;DR: In this article, a linear stability analysis of the Laminar flow of air over water confined between two infinite parallel plates was made and the conditions at which small amplitude surface waves first begin to grow were determined.

TL;DR: In this paper, the cyclotron modes were found to be purely transverse electric at cut-off, gradually changing in character along their propagation curves through hybrid to purely transversal magnetic modes at cyclotic resonance.

TL;DR: In this paper, a non-linear Schrodinger equation for Langmuir waves is derived by using a fluid model for the electrons, while both a fluid and a Vlasov formulation are considered for the ion dynamics.
