摘要

具有自变$\Phi$的群$G$的代数映射环$M_{\Phi }$是稳定字母共轭执行$\Phi$的$G$的HNN-扩展。我们将 $M_{\Phi }$ 的 Dehn 函数按照 $\Phi$ 对一些直角阿汀群(RAAGs)$G$ 进行分类,包括所有 $3$-生成器的 RAAGs 和所有 $k,l \geq 2$ 的 $F_k \times F_l$。

Dehn functions of mapping tori of right-angled Artin groups

The algebraic mapping torus $M_{\Phi }$ of a group $G$ with an automorphism $\Phi$ is the HNN-extension of $G$ in which conjugation by the stable letter performs $\Phi$. We classify the Dehn functions of $M_{\Phi }$ in terms of $\Phi$ for a number of right-angled Artin groups (RAAGs) $G$, including all $3$-generator RAAGs and $F_k \times F_l$ for all $k,l \geq 2$.
