两类八阶BCK-代数的计数问题

Two Classes of 8-order BCK-Agebra

主要利用BCK-代数的定义和BCK-代数的性质,把二类七阶链状BCK-代数作为子代数进行了扩张.满足运算表一的七阶链状BCK-代数扩张成的八阶链状BCK-代数共四个,满足第二类运算表的七阶链状BCK-代数扩张成八阶链状BCK-代数共有三个.

This paper mainly uses the definition of BCK-algebra and the nature of BCK-algebra to expand the two classes of 7-order chain BCK-algebra which is used as the subalgebra into the 8-order chain BCK-algebra.The first 7-order chain BCK-algebra＇ s operational table is expanded into four 8-order chain BCK-algebras. The second 7-or- der chain BCK-algebra＇ s operational table is expanded into three 8-order chain BCK-algebras
