Complex Networks Collaboratory

Welcome to the CX-NETS web-site. This is the virtual collaboratory of three research groups that despite their far apart geographical locations pursue the same research agenda in close collaboration. The web-site is also intended as an information exchange points with links to conferences, tools and references useful for the network science community.

Research keywords: Complex networks, Internet, WWW, Epidemic modeling, Large-scale infrastructures, non-equilibrium statistical physics, complex systems, self-organization.
