Embedding universal covers of graph manifolds in products of trees
We prove that the universal cover of any graph manifold quasi-isometrically embeds into a product of three trees. In particular, we showthat the Assouad-Nagata dimension of the universal cover of any closed graphmanifold is 3, proving a conjecture of Smirnov.
