Garside幺半群与可分性幺半群

Garside monoids vs divisibility monoids

Matthieu Picantin

摘要:

整除幺半群(分别为Garside monoid)是Mazurkiewicz迹monoid(resp.球面Artin monoid),即monoid,其中底层格的分配性(分别为公倍数的存在)被保持为假设,但是生成元之间的关系不被认为必须是交换(分别地,Coxeter类型)。在这里,我们表明,这些幺半群的拟中心可以类似地研究和描述,然后我们展示了两类幺半群之间的交集。

英文摘要:

Divisibility monoids (resp. Garside monoids) are a natural algebraic generalization of Mazurkiewicz trace monoids (resp. spherical Artin monoids), namely monoids in which the distributivity of the underlying lattices (resp. the existence of common multiples) is kept as an hypothesis, but the relations between the generators are not supposed to necessarily be commutations (resp. be of Coxeter type). Here, we show that the quasi-center of these monoids can be studied and described similarly, and then we exhibit the intersection between the two classes of monoids.
