摘要 讨论了一类具有双参数的高阶半线性奇摄动椭圆型方程的边值问题.在适当的假设下,构造了解的形式渐近展开式,并且利用不动点定理,研究了边值问题解的存在性和渐近性态. The boundary value problem of a class of singularly perturbed asymptotic solutions for higher order semilinear elliptic equations with two parameters is considered.Under some suitable conditions,a formal asymptotic expansion of the solution is constructed.By using the fixed theorem,the existence and asymptotic behavior of the solution are studied.
