초록본문(Abstract) | For a compact (weakly) special square complex, the intersection complex which is a certain complex-of-group decomposition structure of its fundamental group is a well-defined invariant under quasi-isometry. In this talk, we use this invariant to classify quasi-isometry types of 2-braid groups of circumference 1 graphs. As an application, we also classify quasi-isometry types of 4-braid groups of trees. This is a joint work with Sangrok Oh(University of the Basque Country). |
