The Energy Transport and the Drift Di usionEquations as Relaxation Limits of theHydrodynamic Model
نویسندگان
چکیده
Two relaxation limits of the hydrodynamic model for semiconductors are investigated. Using the compensated compactness tools we show the convergence of (scaled) entropy solutions of the hydrodynamic model to the solutions of the energy transport and the drift{diiusion equations, according respectively to diierent time scales.

Zero - Relaxation - Time Limits in theHydrodynamic Equations for Plasmas
A rigorous proof of the zero-relaxation-time limits in the hydrodynamic equations for plasmas is given. The equations consist of the Euler equations for the electrons and/or ions coupled with a linear or nonlinear Poisson equation. The proof is based on high energy estimates for the Euler equations and appropriate compactness arguments. The theorem is valid for all adiabatic states for both ele...
