1) countable complementary space
可数补空间
1.
In this paper,we discuss some topological invariant property,including connectedness separation property,compactness and countalbility,in finite complementary space and countable complementary space.
本文讨论了有限补空间与可数补空间的连通性、分离性、紧性及可数性等拓扑不变性质。
2) countable complementary topological space
可数补拓扑空间
3) complemented subspace
可补子空间
1.
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。
2.
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。
4) topologically complemented subspace
拓扑可补子空间
