加法可换可消半环的一个结构定理及应用 总被引:1,自引:0,他引:1
半环是一种有很好实际背景和应用前景的代数结构,尤其对于计算机语言的研究有极为重要的作用。因此,对半环的研究越来越引起人们的关注。本文首先证明了每个加法可换可消半环有一个包环,然后在此基础上证明了它们是多重线性等价的,最后证明了加法可消的交换半坏上的Levitzki-Amitsur定理。 相似文献

Semirings have been studied by various researchers either in an attempt to broaden the techniques coming from semigroup theory or generalization of group theory and ring theory. From an algebraic point of view, semirings provide the most natural generalization of the theory of rings. In this article, we generalize some of the results of Lorenz and Passman (1979) for semirings with finite group action on them. 相似文献

In this paper, we introduce and investigate semicorings over associative semirings and their categories of semicomodules. Our results generalize old and recent ones on corings over rings and their categories of comodules. The generalization is not straightforward and even subtle at several places due to the nature of the base category of commutative monoids which is neither Abelian (not even additive) nor homological, and has no nonzero injective objects. To overcome these and other difficulties, a combination of methods and techniques from categorical, homological and universal algebra is used including a new notion of exact sequences of semimodules over semirings. 相似文献
