$(1+1)$维拟线性wave equations系统行波解的全局稳定性

Global stability of traveling waves for $(1+1)$-dimensional systems of quasilinear wave equations

Louis Dongbing Cha, Arick Shao

摘要:

$(1+1)$维非线性波动方程的一个重要特征是,在适当的非线性代数条件下,它们允许左或右行波。本文证明了$(1+1)$维非线性波动方程组行波解的全局稳定性,给出了行波解的渐近零条件和充分衰减性.我们首先考虑半线性系统作为一个简单的模型问题,然后我们着手处理更一般的拟线性系统。

英文摘要:

A key feature of $(1+1)$-dimensional nonlinear wave equations is that they admit left or right traveling waves, under appropriate algebraic conditions on the nonlinearities. In this paper, we prove global stability of such traveling wave solutions for $(1+1)$-dimensional systems of nonlinear wave equations, given a certain asymptotic null condition and sufficient decay for the traveling wave. We first consider semilinear systems as a simpler model problem; we then proceed to treat more general quasilinear systems.
