摘要
研究一类含有n个参数的高阶非线性微分方程组的正解问题,通过使用Krasnosel'skii不动点定理,在适当的条件下,得到一个和多个正解的存在性的新的结果.
By using Krasnosel＇skii fixed point theorem,a kind of high-order nonlinear ordinary differential systems under suitable conditions is studied.Some new results on the existence of single and multiplicity of positive solutions are obtained.
