L-闭包空间的α_c-准Lindelf性质

The α_c-Pre-Lindelf Properties in L-Closure Spaces

在L-闭包空间中定义了αc-准Lindelf性质,并研究了它的一些基本性质,证明了它对L-闭包空间的闭子集具有遗传性及弱拓扑不变性等。

The concept of the αc pre-Lindelof properties was defined in L-closure spaces,and some of its basic properties studied were.It is proved that many good properties are preserved,such as closely hereditary,weakly topology invariability and so on.
