STATIONARY SOLUTIONS TO THE TWO-DIMENSIONAL BROADWELL MODEL

Journal article, 2020

Existence of renormalized solutions to the two-dimensional stationary Broadwell model in a square with given indata in L-1 is proven. Averaging techniques from the continuous velocity case being unavailable when the velocities are discrete, the approach is based on direct L-1-compactness arguments using the Kolmogorov-Riesz theorem.
