Abstract

Random walks on simple graphs in connection with electrical resistor networks lead to the definition of Markov chains with transition probability matrix in terms of electrical conductances. We extend this definition to an effective transition matrix PijP_{ij} to account for the probability of going from vertex ii to any vertex jj of the original connected graph GG. Also, we present an algorithm based on the definition of this effective transition matrix among vertices in the network to extract a topological feature related to the manner graph GG has been organized. This topological feature corresponds to the communities in the graph.
