Diffusive Corrections to Pn Approximations
Matthias Schaefer, Martin Frank, C. David Levermore
In this paper, we investigate moment methods from a general point of view using an operator notation. This theoretical approach lets us explore the moment closure problem in more d…
Weakly Nonlinear-Dissipative Approximations of Hyperbolic-Parabolic Systems with Entropy
Ning Jiang, C. David Levermore
Hyperbolic-parabolic systems have spatially homogenous stationary states. When the dissipation is weak, one can derive weakly nonlinear-dissipative approximations that govern pertu…
Remarks on the Acoustic Limit for the Boltzmann Equation
Ning Jiang, C. David Levermore, Nader Masmoudi
We use some new nonlinear estimates found in \cite {LM} to improve the results of \cite{GL} that establish the acoustic limit for DiPerna-Lions solutions of Boltzmann equation in t…
