The growth of torus link groups

Yoshiyuki Nakagawa, Makoto Tamura, Yasushi Yamashita

Let $G$ be a finitely generated group with a finite generating set $S$ . For $g \in G$ , let $l_{S} (g)$ be the length of the shortest word over $S$ representing $g$ . The growth series o…

Non-hyperbolic automatic groups and groups acting on CAT(0) cube complex

Yoshiyuki Nakagawa, Makoto Tamura, Yasushi Yamashita

We discuss a problem posed by Gersten: Is every automatic group which does not contain Z+Z subgroup, hyperbolic? To study this question, we define the notion of "n-tracks of length…
