摘要:
对正则FI代数和WBR0代数进行了研究, 讨论了两者之间的关系. 改进了正则FI代数原有的定义;证明了WBR0代数一定是正则FI代数;通过实例说明正则FI代数不一定是WBR0代数;证明了正则FI代数是WBR0代数的一个充分条件是:((a→0)→ b)→ c=((a→ c)→((b→ c)→0))→0.

Abstract:
The properties of WBR0algebra and regular FIalgebra and the relation between them are discussed.The original definition of regular FIalgebra is improved; it is proved that a WBR0algebra is certainly a regular FIalgebra; it is shown by a concrete example that not all regular FIalgebras is a WBR0algebra; it is also proved that a regular FIalgebra having the property of ((a→0)→ b)→ c=((a→ c)→((b→ c)→0))→0 is a WBR0algebra.
