局部凸空间的K强凸性与K强光滑性 总被引:3,自引:0,他引:3
首先引进了局部凸空间K强凸性的概念,它既是Banach空间K强凸性概念在局部凸空间中的推广,又是局部凸空间强凸性概念的自然推广;其次给出了局部凸空间K强凸性概念的对偶概念,即局部凸空间K强光滑性的概念,并得到了K强凸(K强光滑)的局部凸空间的特征刻画;最后,在P-自反的条件下给出了它们之间的对偶定理,即(X,TP)是K强凸(K强光滑)的当且仅当(X′,TP′)是K强光滑(K强凸)的. 相似文献

我们称一个定义在Banach空间E上的连续凸函数f具有Frechet可微性质(FDP),如果E上的每个实值凸函数g≤f均在E一个稠密的Gδ-子集上Frechet可微。本文主要证明了:对任何Banach空间E,均存在一个局部凸相容拓扑p使得1)(E,p)是Hausdorff局部凸空间;2) E上的每个范数连续具有FDP的凸函数均是p-连续的;3)每个p-连续的凸函数均具有FDP ;4)p等价某个范数拓扑当且仅不E是Asplund空间。 相似文献

In the framework of topological vector spaces, we give a characterization of strong Minkowski separation, introduced by Cheng, et al., in terms of convex body separation. From this, several results on strong Minkowski separation are deduced. Using the results, we prove a drop theorem involving weakly countably compact sets in locally convex spaces. Moreover, we introduce the notion of the co-drop property and show that every weakly countably compact set has the co-drop property. If the underlying locally convex space is quasi-complete, then a bounded weakly closed set has the co-drop property if and only if it is weakly countably compact. 相似文献

In this paper we will introduce two other topologies, coarser than the so-called strong topology, on a class of Šerstnev probabilistic normed spaces, and obtain some important properties of these topologies. We will show that under the first topology, denoted by τ0, our probabilistic normed space is decomposable into the topological direct sum of a normable subspace and the subspace of probably null elements. Under the second topology, which is in fact the inductive limit topology of a family of locally convex topologies, the dual space becomes a locally convex topological vector space. 相似文献

Conditions, under which the elements of a locally convex vector space are the moments of a regular vector-valued measure and
of a Pettis integrable function, both with values in a locally convex vector space, are investigated. 相似文献

Daneš' drop theorem is extended to bornological vector spaces. An immediate application is to establish Ekeland-type variational principle and its equivalence, Caristi fixed point theorem, in bornological vector spaces. Meanwhile, since every locally convex space becomes a convex bornological vector space when equipped with the canonical von Neumann bornology, Qiu's generalization of Daneš' work to locally convex spaces is recovered. 相似文献

The purpose of this short technical note is to show that a locally convex topological vector space is normable, if and only
if an important convergence theorem about closed and convex sets holds. This new assumption of normability is related to the
problem of preservation of Hausdorff lower continuity of the intersection of Hausdorff lower continuous, closed and convex
valued correspondences. 相似文献

We consider the vector space of continuousm-homogeneous polynomials between topological vector spaces over a non-trivially valued field of characteristic zero and certain
natural vector topologies on such spaces, and we prove polynomial versions of certain well known theorems of the linear theory
of locally convex spaces.
