Enumeration of Spanning Trees on Generalized Pseudofractal Networks

Abstract: In this paper, we calculate the number of spanning trees on two families of generalized pseudofractal networks with two controllable parameters. The initial state is a complete graph with an arbitrary number of nodes as a generalization of a triangle. In the subsequent steps, each existing edge (newly produced edge) gives birth to finite new nodes. Using the electrically equivalent transformations, we obtain the changes of edge weights of corresponding equivalent networks and derive the relationships for enume… Show more

“…Denote by .G/ the number of spanning trees in G. Enumeration of spanning trees in graphs with certain symmetry and fractals has been widely studied via ad hoc techniques capitalizing on the particular structures [6][7][8][9][10][11]. In general, we often have to resort to Kirchhoff's celebrated matrixtree theorem [12], which asserts that n .G/ equals the product of all nonzero eigenvalues of Laplacian matrix of G, i.e., .G/ D 1 n Q n 1 i D1 i .G/.…”

“…In view of their relevance to diverse aspects of networks and a wide range of applications, spanning trees in networks have become a focus of some recent research [12][13][14][15]. Particularly, in the physics literature a lot of effort has been devoted to enumerating spanning trees in specific self-similar networks by using different techniques.…”
