Query: Coxeter Polynomials of Salem trees   We compute the Coxeter polynomial of a family of Salem trees, and also the
limit of the spectral radii of their Coxeter transformations as the number of
their vertices tends to infinity. We also prove a relation about multiplicities
of eigenvalues of Coxeter transformations of joins of trees.
