The application of renormalized research in a complex network

摘要

In quantum field theory, renormalization can eliminate the problem of infinity in many field theories so that calculation could be completed. In a complex network, many characteristics can be shown at critical state. However, the parameter at critical state is hardly possible to obtain. Renormalization can solve this problem. In this paper, on the basis of renormalization, we describe how to get the parameter via renormalization in a complex network.
