  • Project Abstract: Degree peeling is frequently used to analyze large networks. In particular, previous work has focused on using degree peeling to decompose networks into cohesive subgraphs. These decompositions allow the researcher to focus in on particularly important structures within the network at hand. However, the properties of such structures have not been studied extensively and may be quite large themselves. Here we examine the properties of the structures generated by the iterative edge decomposition of Abello and Queyroi, which are fixed points of degree peeling. We describe how fixed points of degree peeling can be combined to form larger fixed points. Furthermore, we investigate the effects of graph homeomorphism on degree peeling, which can be very drastic. We provide novel methods for minimizing this influence. Combined with the edge decomposition of Abello and Queyroi, our work can be used in network analysis, community detection, and graph visualization.
