Ht. Fan, SELF-SIMILAR SOLUTIONS FOR A MODIFIED BROADWELL MODEL AND ITS FLUID-DYNAMIC LIMITS, SIAM journal on mathematical analysis, 28(4), 1997, pp. 831-851
The existence of self-similar solutions of the Riemann problem for a m
odified Broadwell model is established. Regularity estimates at the si
ngular points of the problem are obtained. The passing of the fluid-dy
namic limit is justified, which yields the Riemann problem for a syste
m of conservation laws.
