Cubic soft sets with applications in BCK/BCI-algebras
نویسندگان
چکیده
The concepts of (internal, external) cubic soft sets, P-cubic (resp. R-cubic) soft subsets, R-union (resp. R-intersection, P-union, Pintersection) of cubic soft sets, and the complement of a cubic soft set are introduced, and several related properties are investigated. We apply the notion of cubic soft sets to BCK/BCI-algebras, and introduce the notion of cubic soft BCK/BCI-algebras. A characterization of cubic soft BCK/BCI-algebras is provided, and we prove that the R-intersection of two cubic soft BCK/BCI-algebras is also a cubic soft BCK/BCI-algebra. 2010 AMS Classification: 06F35, 03G25, 06D72

متن کاملSubalgebras of BCK/BCI-Algebras Based on Cubic Soft Sets
Operations of cubic soft sets including "AND" operation and "OR" operation based on P-orders and R-orders are introduced and some related properties are investigated. An example is presented to show that the R-union of two internal cubic soft sets might not be internal. A sufficient condition is provided, which ensure that the R-union of two internal cubic soft sets is also internal. Moreover, ...

متن کاملSoft Translations and Soft Extensions of BCI/BCK-Algebras
The concept of soft translations of soft subalgebras and soft ideals over BCI/BCK-algebras is introduced and some related properties are studied. Notions of Soft extensions of soft subalgebras and soft ideals over BCI/BCK-algebras are also initiated. Relationships between soft translations and soft extensions are explored.
