摘要 利用在集合上定义映射和不动点原理 ,讨论了偶数阶中立型差分方程正解的存在性 ,根据中立型项取值的不同情况 ,得出了相应方程正解存在的充分条件 . Investigate the existence of positive solution for even neutral differecce equations by using unfixed-point theory and defining the compressed injection on a set.Obtain some sufficient conditions for existence of a positive solution when the neutral term is under different conditions.
