| Abstract: |
| We first discuss some different condensation phenomenon in complex networks.Then we analyze the critical phenomenon of the non-growing Bianconi-Barabsi (B-B) fitness model with fixed number of nodes and links.The analytical studies show that this model displays a condensate-non-condensate phase transition.We numerically simulate its critical behavior in the Boltzmann limit,and find that the non-condensation phase is significantly different from that of the growing B-B model.The corresponding critical temperature Tc and degree distribution P(k) are identified. |
