We show that the additively idempotent semiring \(S_7^0\) has no finite basis for its equational theory. This answers an open problem posed by Jackson et al. (J Algebra 611:211–245, 2022).

加幂等半环 $$S_7^0$$ 是非有限基的
我们证明加性幂等半环\(S_7^0\) 的方程理论没有有限基础。这回答了 Jackson 等人提出的一个悬而未决的问题。 (《代数杂志》611:211–245,2022 年)。
