摘要
运用了初始层函数构造了一类非线性奇摄动抛物型方程初值问题解的渐近展开式 。
In this paper, the asymptotic expansion of the solution of initial value problem for a class of nonlinear singularly perturbed hyperbolic equations which have double initial layer properties is constructed. The uniform valid of the constructed asymptotic expansion of the solution of is proved.
