Bifractality of fractal scale-free networks
Jun Yamamoto, Kousuke Yakubo
The presence of large-scale real-world networks with various architectures has motivated an active research towards a unified understanding of diverse topologies of networks. Such…
A general model of hierarchical fractal scale-free networks
Kousuke Yakubo, Yuka Fujiki
We propose a general model of unweighted and undirected networks having the scale-free property and fractal nature. Unlike the existing models of fractal scale-free networks (FSFNs…
Identification of intrinsic long-range degree correlations in complex networks
Yuka Fujiki, Kousuke Yakubo
Many real-world networks exhibit degree-degree correlations between nodes separated by more than one step. Such long-range degree correlations (LRDCs) can be fully described by one…
A general formulation of long-range degree correlations in complex networks
Yuka Fujiki, Taro Takaguchi, Kousuke Yakubo
We provide a general framework for analyzing degree correlations between nodes separated by more than one step (i.e., beyond nearest neighbors) in complex networks. One probability…
Fractality and degree correlations in scale-free networks
Yuka Fujiki, Shogo Mizutaka, Kousuke Yakubo
Fractal scale-free networks are empirically known to exhibit disassortative degree mixing. It is, however, not obvious whether a negative degree correlation between nearest neighbo…
Structural instability of large-scale functional networks
Shogo Mizutaka, Kousuke Yakubo
We study how large functional networks can grow stably under possible cascading overload failures and evaluated the maximum stable network size above which even a small-scale failu…
