利用不动点定理研究一类椭圆型方程的奇摄动边值问题
Singularly perturbed boundary value problems for elliptic equations via the fixed point theorem
摘要
Abstract
Singularly perturbed boundary value problems for a class of semi-linear second-order elliptic e-quations are studied.The formal approximation of the problem is constructed by using the method of composite expansions,and the existence and asymptotic behavior of solutions are proved by Harten's fixed point theorem.关键词
