Stability of a superposition of shock waves with contact discontinuities for the Jin-Xin relaxation system
摘要:
本文研究了具有小初始扰动的一维Jin-Xin松弛系统的具有接触间断的激波叠加的大时间渐近非线性稳定性,条件是波的强度在相同的阶数下很小.这些结果是由基本的加权能量估计的基础上的波结构和热方程的估计。
英文摘要:
In this paper, we consider the large time asymptotic nonlinear stability of a superposition of shock waves with contact discontinuities for the one dimensional Jin-Xin relaxation system with small initial perturbations, provided that the strengths of waves are small with the same order. The results are obtained by elementary weighted energy estimates based on the underlying wave structure and an estimate on the heat equation.
