Kinetic Invariant Domains and Relaxation Limit from a BGK Model to
Isentropic Gas Dynamics
Florent Berthelin and Francois Bouchut
We obtain rigorously the correspondence between kinetic and
macroscopic invariant domains for a vector kinetic BGK
system considered in a previous paper of the authors.
We establish the convergence, as the relaxation parameter
tends to $0$, to weak entropy solutions of isentropic gas
Key-words: isentropic gas dynamics, kinetic BGK model,
kinetic entropy, kinetic invariant domain, relaxation limit
