Mathematical Physics 2021-12-17 v2 math.MP

Abstract

The paper proves existence of renormalized stationary solutions for a dense class of discrete velocity Boltzmann equations in the plane with given ingoing boundary values. The proof is based on the construction of a sequence of approximations with L1 compactness for the integrated collision frequency and gain term. Compactness is obtained using the Kolmogorov-Riesz theorem.

The conditions in the new version are more general. The end of the proof in Section 4 is changed. The appendis is replace with a reference to the paper where those background results are proved
