In chapter 5, local derivations and local automorphisms of nest subalgebras in von Neumann algebras and local higher cohomology -local 2-cocycles are studied. It is proved that every weakly continuous local derivation, respectively, every weakly local automorphism, of nest subalgebra of a factor von Neumann algebra is a derivation, respectively, an automorphism. Every norm continuous local derivation, respectively, every norm local automorphism, of the nest subalgebra associated to a countable nest in a factor von Neumann algebra is a derivation, respectively, an automorphism. Moreover, it is answered Larson's question. Finally, it is shown that every local 2-cocycle of any von Neumann algebra is a 2-cocycle.

第五章研究von Neumann代数中套子代数的局部导子和局部同构以及von Neumann代数的高维局部映射—局部2-上循环，证明了因子von Neumann代数中套子代数的每一个局部强连续导子和局部强连续同构分别是导子和同构；可数套所对应的套子代数的每一个有界局部导子和有界局部同构分别是导子和同构；同时，部分回答了Larson所提的问题；最后，得到von Neumann代数的每一个局部2-上循环是2-上循环。

Methods: We have respectively done correlation analysis including auto-correlation and cross correlation analysis for 10 derivation electrodes＇ and 21 derivation electrodes＇ EEG data, and acquired each derivation＇s result of auto-correlation analysis and symmetrical left with right derivation＇s result of cross-correlation analysis at different condition and event.

derivation：推导

"xxvii为了确切地回答本文一开始叙述的不同演绎系统(比如欧氏几何与非欧几何)之间具有真值联系的问题,一些逻辑学家曾力图以严格的方式定义"推论"(consequence),它的外延和内涵都要比"推导"(derivation)这个概念更丰富,后者只能说明"可证实"概念,

derivation：导出

它的一个同义词是导出(derivation). 演绎是相对于系统的概念,说一个公式(或语句)是演绎的只是相对于一不定的公理和推理规则的具体系统而言的. 演绎概念是证明概念的概括. 一个证明是语句这样的有穷序列:它的每个语句或是公理或是根据推理规则由前面的语句得出的.
