In chapter 5 we introduce the concepts of topological reflexivity in several topologies, namely, the discrete, the norm, the strong and the weak operator topology. we prove that the spaces of (, ) - derivations on certain operator algebras are topologi - cally reflexive in the weak operator topology. the automorphisms and (, ) - derivations of reflexive algebras in banach spaces are also characterized in this chapter
在第五章中我們引進了在離散拓撲、范數拓撲、強運算元拓撲和弱運算元拓撲下的拓撲自反性,證明了某些運算元代數上( , ) ?導子空間在弱運算元拓撲下是拓撲自反性的,同時我們還刻畫了自反代數的自同構和( , ) ?導子。The first generation spatial analysis database system, sadbs, uses " realms " as expression base of spatial data. it adopts discrete integer coordinate system to solve topological error in spatial database. it also uses multi - index data organization and plane - sweep algorithm, which improve the performance of spatial analysis operations
第一代空間分析數據庫系統sadbs使用realms作為空間數據的表示基礎,它利用離散化的整數坐標系統,解決了空間數據庫的拓撲誤差問題;使用多索引的數據組織方法,引入平面掃描演算法,提高了空間分析操作的性能。We consider the following periodic boundary valve problems ( pbvps ) : where ( i. e., f is continuous as a map from the topological space i + r2 into the topological space r ( of course the topology on i, will be the discrete topology )
考慮下面的周期邊值問題( pbvps ) :其中( f是從拓撲空間i r ~ 2到拓撲空間r (這里的拓撲是離散拓撲)的連續映射)Stzware is a two and three dimension spatial analysis software based on realms math model developed by nuaa, and the two - dimension subset of this software defines spatial data types on 2 - dimension discrete grid, such as point set ( privpoints ), line set ( privlines ) and region set ( privregions ), and implements attribute operation functions of these 3 types and topology analysis functions among these 3 types
Stzware是由南京航空航天大學研製的基於數學模型realms的二三維空間分析軟體,其中的二維子集定義了二維平面離散網格上的空間數據類型:點集( privpoints ) 、線集( privlines )和區域集( privregions ) ,並實現了這三種類型的屬性操作函數和這三種類型間的拓撲分析函數。分享友人
