摘要
在内部算子、闭包算子和近似算子概念的基础上,研究了内部算子、闭包算子与自反传递 粗集中近似算子的复合以及交叉复合,得到了它们之间的一些关系.
On the basis of interior operators, closure operators and approximate operators, the compound and overlapping compound of interior operators, closure operators and approximate operators are studied in reflexives and transitive rough sets. Some connections among them are obtained.
