Subalgebras of BCKBCI-Algebras Based on Cubic Soft Sets

الملخص EN

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, some properties of cubic soft subalgebras of BCK/BCI-algebras based on a given parameter are discussed.
