由幂等元生成的半环

Semirings generated by idempotents

David Dolžan

AI总结:

该研究在半环的幂等元正交补、幂零元中心性等假设下,分别证明了幂等元乘法生成半环的交换布尔性与加法生成半环的交换性,并通过例子说明相关假设不可省略。

摘要:

我们证明:若半环中每个幂等元都存在正交补,则由其幂等元乘法生成的半环是交换且布尔(Boolean)的。我们还证明:若半环中每个幂等元都有正交补,且半环中所有幂零元都是中心的,则由其幂等元加法生成的半环是交换的。我们同时给出例子,说明关于幂等元正交补存在性、幂零元中心性的假设不可省略。

英文摘要:

We prove that a semiring multiplicatively generated by its idempotents is commutative and Boolean, if every idempotent in the semiring has an orthogonal complement. We prove that a semiring additively generated by its idempotents is commutative, if every idempotent in the semiring has an orthogonal complement and all the nilpotents in the semirings are central. We also provide examples that the assumptions on the existence of orthogonal complements of idempotents and the centrality of nilpotents cannot be omitted.
