In this paper we introduce the notion of operator semirings of a -semiring to study -semirings. It is shown that the lattices of all left (right) ideals (two-sided ideals) of a -semiring and its right (respectively left) operator semiring are isomorphic. This has many applications to characterize various -semirings.AMS Subject Classification (2000): 16Y60, 16Y99 相似文献

从满足ACC的任何偏序集是pre-CPO出发,研究了满足ACC的偏序集上的定向集,并由此给出满足ACC的*-λ-半环的一些性质.证明了S是满足ACC的*-λ-半环,则S是局部闭*-半环和连续*-半环.进一步得到任何满足ACC的*-λ-半环是对称*-λ-半环。 相似文献

本文给出了构造弱归纳*-半环上任意两个二元仿射映射的联立不动点的一种方法,并证明了对于归纳*-半环上的二元仿射映射,这种构造实际上给出了其最小联立前不动点. 相似文献

研究了交换的弱归纳*-半环S上的二阶方阵半环S2×2.给出S2×2仍为弱归纳的一个充分条件.即若S2×2是λ-半环,则S2×2是弱归*-半环.应用这一结果可以证明S上的二元仿射映射存在最小的联立不动点,部分回答了相关文献中的公开问题. 相似文献
