Graph of groups decompositions of graph braid groups
Daniel Berlyne
We provide an explicit construction that allows one to easily decompose a graph braid group as a graph of groups. This allows us to compute the braid groups of a wide range of grap…

Hierarchical hyperbolicity of graph products
Daniel Berlyne, Jacob Russell
We show that any graph product of finitely generated groups is hierarchically hyperbolic relative to its vertex groups. We apply this result to answer two questions of Behrstock, H…
