On the spectra of some graphs like weighted rooted trees

Let G be a weighted rooted graph of k levels such that, for j ∈ {2, ..., k}(1)each vertex at level j is adjacent to one vertex at level j - 1 and all edges joining a vertex at level j with a vertex at level j - 1 have the same weight, where the weight is a positive real number;(2)if two vertices at...
