The author gives an analysis of the mathematical properties of non-homogeneous networks when zero density perturbations are added to homogeneous Cayley trees. For some specific perturbations one is able to write down and, in some cases, solve the secular equation. The Perron Frobenius eigenvector is obtained as the infinite volume limit of the finite volume Perron Frobenius eigenvectors and there is an extensive discussion of its properties. Conditions under which the perturbed graph is recurrent or transient are indicated, too. The whole investigation in this paper is related to the results obtained in [F. Fidaleo, D. Guido and T. Isola, “Bose Einstein condensation on inhomogeneous amenable graphs”, Infin. Dimens. Anal. Quantum Probab. Relat. Top. 14, No. 2, 149–197 (2011; Zbl 1223.82012)].
