摘要 利用锥上的不动点定理,讨论了2n阶时滞微分方程正解的存在性和多重性,得到了方程至少有一个正解、两个正解及三个正解的存在性结果。 This paper presents a study on the existence of positive solutions for 2n-order delay differential equations by using the fixed point theorem in cone and Leggett-Williams point theorem.The result showed there are one,two or three positive solutions of the equation.
