# On stationary solutions to normal, coplanar, discrete Boltzmann equation models

@inproceedings{LArkeryd2020OnSS, title={On stationary solutions to normal, coplanar, discrete Boltzmann equation models}, author={L.Arkeryd and A.Nouri}, year={2020} }

The paper proves existence of renormalized solutions for a class of velocity-discrete coplanar stationary Boltzmann equations with given indata. The proof is based on the construction of a sequence of approximations with L1 compactness for the integrated collision frequency and gain term. L1 compactness of a sequence of approximations is obtained using the Kolmogorov-Riesz theorem and replaces the L1 compactness of velocity averages in the continuous velocity case, not available when the…
