直角群和幺半群的增长性

Growth in Right-Angled Groups and Monoids

Jayadev S. Athreya, Amritanshu Prasad

摘要:

我们推导了图幺半群、直角Artin群和直角Coxeter群的球面生成函数之间的函数关系。我们利用这些关系来表示直角Artin群的球生成函数的定义图的团多项式。我们还描述了这些结构的测地线生成函数的计算算法。

英文摘要:

We derive functional relationships between spherical generating functions of graph monoids, right-angled Artin groups and right-angled Coxeter groups. We use these relationships to express the spherical generating function of a right-angled Artin group in terms of the clique polynomial of its defining graph. We also describe algorithms for computing the geodesic generating functions of these structures.
