近似空间的两种刻画
Two characterizations of approximation spaces
摘要
Abstract
To study the relationship between mathematical structures and rough set ,by using to‐pological and categorical theory ,it is proved that the category of interior space is isomorphic to the category of approximation space ,and the category of closure space is also isomorphic to the category of approximation space ,and two characterizations of approximation space are ob‐tained .Finally some categorical properties of closure spaces are discussed .关键词
