| Outline of Final Research Achievements |
The internet, neuronal networks, sending/receiving relationship of e-mails, and human contacts are described and analyzed as complex networks. They usually evolve with time, changing their connections between vertices, and it is highly important to analyze their underlying spatio-temporal properties in observed data.
We have focused on networks whose structures vary with time, and proposed a distance that can appropriately evaluate the amount of change from the perspective of spatio-temporal structures of networks. We applied our method to mathematical models and real network data, and showed that the proposed distance can detect the properties of networks that cannot be detected by the conventional distances.
