给出了软BCK代数的广义交运算和广义并运算,证明了一个集合X上的一族软BCK代数{(Fi,Ai)}i∈I的广义交和一族软BCK代数{(Fi,Ai)}i∈I(对任意i,j∈I,i≠j有Ai∩Aj=φ)的广义并仍然是X上的软BCK代数,集合X上的软BCK代数(G,B)的一族软子代数的交、广义交和广义并仍是(G,B)的软子代数。
Generalized intersection and generalized union of a class of soft BCK algebras are studied,it is proved that the generalized intersection of a class of soft BCK algebras {(Fi,Ai)}i∈I and the generalized union of a class of soft BCK algebras {(Fi,Ai)}i∈I (for any i,j∈I,i≠j,Ai∩Aj=φ) on a set X are also BCK algebras on X,the intersection,generalized intersection and generalized union of a class of soft sub-algebras of a soft BCK algebra(G,B) on X are also soft sub-algebras of(G,B).
