The optimal condition for a class of vector extremum problem in ordered linear space
序线性空间一类向量极值问题的最优性条件
In the partially ordered linear spaces , we discuss the uniqueness and existence of fixed points for some nonmonotone operators in the partially ordered linear spaces without the assumption of continuity and compactness and upper - lower solutions of operators . the results obtained improve and generalize the major results in reference [ 1 ]
研究了半序线性空间中一类非单调映射的不动点的存在唯一性及其迭代过程,对所述的映射没有作连续性、紧性或具有上、下解的假定.其推论推广和改进了文献[ 1 ]中的主要结果
