No one can deny that we now live in a world whose interconnectedness has increased over time. The analysis of these networks and their complexity has thus become an important issue in understanding the world. In this context, research on complex networks, such as promoted by PCI Network Science, is becoming more important than ever. Understanding the complex networks that exist or that we are building, the local/global and multiscale interactions, requires both a multidisciplinary approach to share tools, methods and concepts, and interdisciplinary approaches that achieve innovative scientific integration. PCI Network Science covers both theoretical and applied research related to complex networks: social networks, technological networks, historical networks, ecological networks, biological networks, animal networks, … PCI Network Science considers both quantitative and qualitative methods as long as they are related to network analysis. more (...)
