摘要
粗糙集的代数刻画是理论研究中最活跃的一个分支。论文将分子格中的预拓扑引入到粗集理论中,给出了由预拓扑导出的近似算子及其性质,讨论了近似算子与预拓扑之间的关系。
Algebraic properties of rough sets is the most active branch among the theoretical research. This paper led molecular lattices and their pretopological onto rough set theory, the approximation operators and their properties based on pretopological are advanced. Consequently, The relation between the approximation operators and pretopological are established.
