Abstract:

We present the mathematical structure and characteristics of two-variables function S-rough sets. We also propose a relation theorem of two-varibles function S-rough sets with one-variable function S-rough sets,S-rough sets, two-variables function rough sets and Pawlak rough sets.

Key words: two-variables function S-rough set, one-variable function S-rough set, two-variables function rough set, relation theorem
