From the Difference of Structures to the Structure of the Difference

Figure 4

Analysis of the world-wide air transport network. (Top) Evolution of the structure of changes, for the top- (left panel) and top- (right panel) networks. The colour of each point represents the of the -value of the test, with light (dark) shades indicating random (structured) changes. Bottom left: evolution of the structure, for the top- networks, as yielded by the normalised global overlap . Bottom right: scatter plot comparing the results yielded by the and , for the top- networks.
