无平方二部图上与无三角形图和锥相关的Artin-Tits群的非圆柱双曲性

Acylindrical hyperbolicity of Artin-Tits groups associated to triangle-free graphs and cones over square-free bipartite graphs

Motoko Kato, Shin-ichi Oguni

摘要:

证明了每一个不可约Artin群的中心商要么是虚循环的,要么是非圆柱双曲的.本文对无三角形图的Artin群和无平方二部图上的锥的大型Artin群证明了这个猜想。事实上,我们根据Brady和McCammond的结果处理了已知为CAT(0)群的Artin群。

英文摘要:

It is conjectured that the central quotient of every irreducible Artin group is either virtually cyclic or acylindrically hyperbolic. We prove this conjecture for Artin groups associated to triangle-free graphs and Artin groups of large type associated to cones over square-free bipartite graphs. In fact, we treat Artin groups that are known to be CAT(0) groups by a result of Brady and McCammond.
