Complemented space

As pointed by the author, the sum of two complemented subspaces of Banach space X may not be complemented space of X ; however, when P and Q are all continuous linear projection operators on X and PQ are strictly singular operators, PX+QX are complemented.

指出Ｂａｎａｃｈ空间Ｘ的两个可补子空间之和未必再是Ｘ的可补子空间，但当Ｐ和Ｑ都是Ｘ上连续线性投影算子且ＰＱ是严格奇异算子时，ＰＸ＋ＱＸ是可补的。

A Banach space X with a unconditional basis {xn} is said to have the property P if, every bounded block basis sequence of {xn} spans a complemented subspace of X.

称一个带无条件基｛ｘｎ｝的Ｂａｎａｃｈ空间有性质Ｐ，如果｛ｘｎ｝的每一有界块基序列都张成Ｘ的可补子空间。

The paper aims to analyze the mechanism from individual location choice to agglomeration, and discusses the condition of agglomeration in the viewpoint of spatial complementary.

本文旨在探索个体选址行为到实现空间集聚的内在机制,并基于空间互补视角探讨了空间集聚的条件——自然的抑或人为造成的空间互补利益可以加速空间集聚,并使之在这一区位形成维持和锁定效应。
