  Abstract:  

Suppose G = (V, E) is a graph. The sequence v1v2…vt(vt = v1) is called a closed walk with length t - 1 in G if vi''''s are in V(G) and vivi+1 Î E(G). In this paper, the number of closed walks with length k, Cw(G,k), for two classes of denderimers are computed.

 

Keywords: Dendrimer, closed walk. graph spectrum, Estrada index.
