Every weakly countably compact closed convex set in a locally convex space has the quasi-weak drop property. 局部凸空间中每个弱可数紧闭凸集具拟弱滴状性质.
Projection onto convex sets (POCS) is used in this paper. 本文采用POCS方法进行超分辨率图像复原研究。
The problem of the existence of a cone subdifferential for the cone convex set valued maps in the locally convex, linear and topological vector space is discussed. 在局部凸线性拓扑向量空间讨论了一种锥凸集值映射的锥次微分的存在性问题
The existence and uniqueness of the element of best approximation on sequentially weak compact convex set in the normed linear spaces are studied,the conclusion of which improves and generalizes the existing result of Erwin kreysziy. 研究了在严格凸赋范线性空间上无穷维弱列紧凸子集的最佳近似元的存在与唯一性，所得结论改进和推广了Erwin Kreysziy 等已有的结果。
