Abstract:

The core-periphery structure is an important and common structure in complex networks, however, there is little relevant research on it. In order to study and find some properties of the coreperiphery structure in complex networks, we analyze the structure of the random block model. On this basis, we propose a scale-free network evolving model with core-periphery structure. Theoretical and numerical analysis verify that the proposed model has sound scale-free characteristics and a core-periphery structure and its compactness is adjustable. This model can provide basis for further study on the characteristics of the core-periphery structure in complex networks.

Key words: complex networks, core-periphery structure, scale-free, evolving model
