Network stability, dynamics and spatial games

Description:

This complex project is aimed to understand the rules of network evolution and the emergence of network complexity. In hope to find key aspects in this multi-task process, we combine three independent, but interrelated approaches.

• First, we keep in mind our observation, which showed the generality of the stabilizing role of weak-links in a wide variety of real world networks and try to give a more exact meaning of this statement.
• Second, we analyze the development of cooperation in repeated games between agents situated on nodes of various networks using our refined knowledge on the topology of complex and large real world networks.
• Third, we develop analytical tools to follow network dynamics and evolution in hope to link these processes to the emergence of game strategies.
