- Some properties of paracompact locally cosmic spaces
空间的一些性质 - Theorem 4 space x is a cosmic space if and only if x is a - compact space with a - weakly hereditarily closure - preserving pair - networks
, x 。具有。遗传闭包保持双网络当且仅当或者每x ‘ ,是cosmic空间且除可数个a外, x 。 - It is not in cosmic space which is empty of anything , but in the world which is full of such familiar things as grasses , flowers , birds , utility poles and signals
那里并不是真空的宇宙空间,而是一样是有花草、鸟、电线杆和信号等亲切事物的世界。 - On its basis , gao zhimin introduced the concept of pair - network and proved that a space has - locally finite pair - networks if and only if it is cosmic space in 1986
在此基础上, 1986年高智民引入了双网络( pair - network )的概念,证明了具有局部有限双网络的正则空间等价于cosmic空间。 - Yan pengfei proved that a space has point countable pair - networks if and only if it is cosmic space in 1999 further and put forword the question how we depict the space with - hereditarily closure - preserving pair - networks on the basis of acquirement of interested characteristics of the space with - hereditarily closure - preserving cs * - networks
1999年燕鹏飞进一步证明了具有点可数双网络的正则空间也等价于cosmic空间,并在获得了具有遗传闭包保持cs ~ *双网络( cs ~ * - network )空间的有趣的内在特征之后提出问题:如何刻画具有遗传闭包保持双网络的正则空间
