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…

Numerical schemes for a multi-species quantum BGK model
Gi-Chan Bae, Marlies Pirner, Sandra Warnecke
This work is devoted to the numerical implementation of the quantum Bhatnagar- Gross-Krook (BGK) model for gas mixtures consisting of classical and quantum particles (fermions, bos…
