摘要
利用Mnch不动点定理,本文研究了Banach空间中无界区域上一阶微分方程组的边值问题,得到其非负无界解的存在性。
In this paper, a boundary value problem for first order differential systems on unbounded domain is adressed by means of the MSnch fixed point theorem in a Banach space, and the existence of its unbounded nonnegative solutions is obtained.
