The phase space density f of a dilute gas evolves according to the Boltzmann equation. In the physically relevant case, the gas would be confined to a subset Î© âŠ‚ R, and then f(x, v, t) : Î©Ã—R3Ã—R+ â†’ R,â€¦ (More)

Let Î› be a ring endowed with an involution a 7â†’ Ã£. We say that two units a and b of Î› fixed under the involution are congruent if there exists an element u âˆˆ Î›Ã— such that a = ubÅ©. We denote by H(Î›)â€¦ (More)

The construction of discrete velocity models or numerical methods for the Boltzmann equation, may lead to the necessity of computing the collision operator as a sum over lattice points. The collisionâ€¦ (More)
