KdV limit of the Euler-Poisson system

Analysis of PDEs 2014-01-15 v2

Abstract

Consider the scaling ε1/2(xVt)x, ε3/2tt\varepsilon^{1/2}(x-Vt)\to x,\ \varepsilon^{3/2}t\to t in the Euler-Poisson system for ion-acoustic waves \eqref{equ1}. We establish that as ε0\varepsilon\to 0, the solutions to such Euler-Poisson system converge globally in time to the solutions of the Korteweg-de Vries equation.
