Regularity of the 90-velocity model of the Boltzmann equation
The authors study discrete velocity models of the Boltzmann equation and establish the existence of various regular models that are invariant under the symmetry group \(G=A_ 5\times I\), where \(A_ 5\) is the icosahedron group and I is the group of order two generated by the central inversion. Here they show the regularity of the 90-velocity model and claim that a series of regular discrete models can be outlined by induction.
