摘要
运用非线性电报方程解的渐近理论,讨论了具有初边值条件的电报方程utt-uxx+u+εu2=0解的适定性和时间无穷大时其渐近近似解的合理性,同时使用偏微分方程双扰动方法,研究了在O(ε)近似条件下解的渐近性质.
The aim of this paper is to establish the well-posedness and asymptotic validation of solution for the telegraph equation utt-uxx+u+εu2=0by using the asymptotic theory. Meanwhile by using the two-time perturbation techniques, the approximation properties of the solution are inverstigated under the approximate condition 0(ε).
