生成为半环的格序阿贝尔群

Lattice-ordered abelian groups finitely generated as semirings

Vítězslav Kala

摘要:

格序群($\ell$ -群)$G(\oplus, \vee, \wedge)$可以自然地看作半环$G(\vee,\oplus)$ .本文给出了由半环生成的(交换)$\ell$ -群的完全分类,首先证明了每个这样的$\ell$ -群都有一个序单位,这样我们就可以利用Busaniche,Cabrer和Mundici [8]的结果.然后,我们仔细地分析它们在我们的设置中的构造,以获得与有根树相关联的某些$\ell$ -群的分类(定理4.1)。这个分类结果有许多重要的应用:例如,它意味着一个具有幂等加法的广义生成的理想单(交换)半环$S(+, \cdot)$的分类,并提供了关于广义生成的理想单(交换)半环的结构的重要信息,有助于进一步推进[2],[15]中讨论的猜想1.1。

英文摘要:

A lattice-ordered group (an $\ell$-group) $G(\oplus, \vee, \wedge)$ can be naturally viewed as a semiring $G(\vee,\oplus)$. We give a full classification of (abelian) $\ell$-groups which are finitely generated as semirings, by first showing that each such $\ell$-group has an order-unit so that we can use the results of Busaniche, Cabrer and Mundici [8]. Then we carefully analyze their construction in our setting to obtain the classification in terms of certain $\ell$-groups associated to rooted trees (Theorem 4.1). This classification result has a number of important applications: for example it implies a classification of finitely generated ideal-simple (commutative) semirings $S(+, \cdot)$ with idempotent addition and provides important information concerning the structure of general finitely generated ideal-simple (commutative) semirings, useful in obtaining further progress towards Conjecture 1.1 discussed in [2], [15].
