Hydrodynamic Limit of the Boltzmann Equation toward Generic Riemann Solutions with Shocks
Mingi Choe, Moon-Jin Kang, Moon-jin Kang +1
We establish the hydrodynamic limit of the one-dimensional Boltzmann equation with hard-sphere collisions toward Riemann solutions of the compressible Euler system. The Riemann sol…

Quantitative Closure Analysis toward Ideal Fluids
Gi-Chan Bae, Chanwoo Kim
We establish the incompressible low--Mach/high--Reynolds limit for the Boltzmann equation for a broad class of initial data, without recourse to any asymptotic expansion. Exploitin…
