摘要
The Anderson-Witting model is a relativistic generalization of the Bhatnagar-Gross-Krook model which is well-known as the relaxation-time approximation of the celebrated Boltzmann equation. In this paper, we address the stationary boundary value problems to the Anderson-Witting model in slab geometry. We prove the existence of unique stationary solution to the boundary value problem of the Anderson-Witting model in a bounded interval with the inflow boundary data when the gas is sufficiently rarefied.
