研究了一类奇摄动拟线性边值问题,在适当的条件下,用合成展开法构造出该问题的形式近似式,并应用不动点定理证明了激波解的存在性及其渐近性质.
Some singularly perturbed quasilinear boundary value problems with interior shock layer properties are studied under certain conditions, the formal approximation of the problem is constructed using the mothed of composite expansions, and the existence and asymptotic behavior of solutions are proved by the fixed point theory.
