Query: The bridge number of arborescent links with many twigs   We prove the meridional rank conjecture for arborescent links associated to
plane trees with the following property: all branching points carry a straight
branch to at least three leaves. The proof involves an upper bound on the
bridge number in terms of the maximal number of link components of the
underlying tree, valid for all arborescent links.
