摘要
本文考虑有序Ｂａｎａｃｈ空间中形如：ｘ＝ｙ＋Ｋｆ（·，Ｐ＿１ｘ，…，Ｐ＿ｎｘ）的算子方程，利用一定的不动点定理，得到了这类方程存在正解的某些充分条件。
In this paper we consider operator equations in ordered Banach spaces of the formx=y+Kf· ,P_1X,···,P_nX). By means of some fixed point theorems, we obtain somesufficient conditions for such an equation to have positive solutions.
