On soft lifts and soft transformations induced by soft sets-(II)

초록

We introduce and investigate the notions of some soft lifts (F←, F→, g+; g-) and soft U-transformation combined by F←, F→ and a mapping between parameter sets. We also investigate properties for such notions and the relations among soft mappings, soft lifts and soft U-transformations. In particular, we show that a soft U-transformation preserves some properties between given soft sets. We will also show that a soft U-transformation induces a soft transformation under a given condition. And, the results will be applied to study data mining, knowledge discovery, knowledge reduction and information systems eectively. © 2016 Won Keun Min and Young Key Kim.
