无处稠密集的等价性质研究

Equivalent Property Study on Nowhere Dense Set

对已有的无处稠密等价性质进行阐述和补充性研究,得出与无处稠密等价的两个新的结论,使无处稠密集与稠密集之间建立起了等价关系.

The authors have, on the basis of interpretation of equivalent property study on nowhere dense set, made a complementary study to it and put forward two new conclusions of nowhere dense equivalent property, which establish an equivalent property relation between nowhere dense set and dense set.
