摘要
作者通过推广D-空间思想得到对偶性质,并给出对偶离散空间的定义,说明ω1是对偶离散的。之后作者通过定义了一个称为O-粘集的偏序关系,从而得到了对偶离散空间的一个充分条件,并提出了问题:对偶离散空间的并是否是对偶离散的,及线性lindelof加对偶离散是不是lindelof的。
The paper talk about the defination and some conclusions of dually discret space and offer the problem of dually discret space.If the are readers intresting it,he or she can discus with the author
