THE ASYMPTOTIC BEHAVIOR OF SOLUTIONS OF INITIAL VALUE PROBLEM TO SYSTEM OF GAS DYNAMICS WITH VISCOSITY

This paper considers the system where with where provided orThe traveling wave solution of problem (A), (B) is proved to be asymptoically stable when (C)_1, (C)_2 are satisfied and rarefaction wave solution is proved to be asymptotical when (C)_3, (C)_4 are satisfied, provided that the initial disturbance is suitably small and of zero constant component. The proof is given by the elemental L~2 energy method.

具有某种源气体动力学方程组定解问题整体解的渐近性

对于方程组(1.1)的齐次形式(f(u)=0),Kazhikhov 证明了初边值问题(1.1)—(1.3)的解的整体存在性以及渐近性.随后,陈贵强、陆云光对于非齐次方程组(1.1)的初边值问题的解的整体存在性给予了证明.本文研究方程组(1.1)的初边值问题整体解的渐近性.
