Comments welcome!", "categories": [ "math.GR", "math.GT" ], "abstract": "Garside groups are combinatorial generalizations of braid groups which enjoy many nice algebraic, geometric, and algorithmic properties. In this article we propose a method for turning the direct product of a group $G$ by $\\mathbb{Z}$ into a Garside group, under simple assumptions on $G$. This method gives many new examples of Garside groups, including groups satisfying certain small cancellation condition (including surface groups) and groups with a systolic presentation. Our method also works for a large class of Artin groups, leading to many new group theoretic, geometric and topological consequences for them. In particular, we prove new cases of $K(\\pi,1)$-conjecture for some hyperbolic type Artin groups.", "revisions": [ { "version": "v1", "updated": "2023-05-19T12:02:53.000Z" } ], "analyses": { "subjects": [ "20E42", "20F36", "20F55", "05B35", "06A12", "20F65", "05C25" ], "keywords": [ "garside structures", "garside group", "applications", "hyperbolic type artin groups", "small cancellation condition" ], "note": { "typesetting": "TeX", "pages": 38, "language": "en", "license": "arXiv", "status": "editable" } } }
