摘要
给出Hilbert空间到其自身不具有关于锥的例外族的映射条件 ,利用Hilbert空间可表为闭凸锥与负对偶锥的特点研究映射关于锥的例外簇的特性 ,证明了可通过映射在某紧凸子集上的性态判断其例外簇的存在与否 。
The conditions that mappings from a Hilbert space to itself have no exceptional family with respect to a cone are presented. The conception is based on the feature of Hilbert space that can be expressed as the sum of a closed convex cone and its negative dual cone. The results obtained show that characteristics of mappings in a compact subset of cone determine whether or not the exceptional family exists. Meanwhile, problems of no exceptional family on the several kinds of monotone mappings are studied.
