Global solutions to the isothermal Euler-Poisson plasma model. (English) Zbl 0817.76102
Summary: Global existence of a solution to the system of isothermal one- dimensional Euler equations for electrons and ions coupled by the Poisson equation is proved using Glimm scheme. The key point is the use of the almost conservation of charge for estimating the total variation of the electric field.
