摘要
给出了二元函数单向S-粗集的数学结构和特性.提出了二元函数单向S-粗集与一元函数单向S-粗集、单向S-粗集的关系定理,二元函数单向S-粗集与二元函数粗集的关系定理.最后以实例说明二元函数单向S-粗集的存在.
The mathematical structure and characteristics of two-variables function one direction Srough sets are given in the paper. The relation theorem of two-varibles function one direction S-rough sets with one-variables function one direction S -rough sets and one direction S -rough sets are put forward. The relation theorem of two-variables function one direction rough sets with two-variables function rough sets are also presented. At the end of the paper,a suitable example is given.
