Robustness of Attractor States in Complex Networks with Scale-free Topology

Shu-ichi Kinoshita, Kazumoto Iguchi, Hiroaki S. Yamada

We study the intrinsic properties of attractors in the Boolean dynamics in complex network with scale-free topology, comparing with those of the so-called random Kauffman networks.…

General Connectivity Distribution Functions for Growing Networks with Preferential Attachment of Fractional Power

Kazumoto Iguchi, Hiroaki Yamada

We study the general connectivity distribution functions for growing networks with preferential attachment of fractional power, , using the Simon's method. We fi…

Boolean Dynamics of Kauffman Models with a Scale-Free Network

Kazumoto Iguchi, Shuichi Kinoshita, Hiroaki S. Yamada

We study the Boolean dynamics of the "quenched" Kauffman models with a directed scale-free network, comparing with that of the original directed random Kauffman networks and that o…

Rugged Fitness Landscapes of Kauffman Model with a Scale-Free Network

Kazumoto Iguchi, Shuichi Kinoshita, Hiroaki Yamada

We study the nature of fitness landscapes of 'quenched' Kauffman's Boolean model with a scale-free network. We have numerically calculated the rugged fitness landscapes, the distri…

Vibrational modes and spectrum of oscillators on a scale-free network

Kazumoto Iguchi, Hiroaki Yamada

We study vibrational modes and spectrum of a model system of atoms and springs on a scale-free network in order to understand the nature of excitations with many degrees of freedom…

Exactly solvable scale-free network model

Kazumoto Iguchi, Hiroaki Yamada

We study a deterministic scale-free network recently proposed by Barabási, Ravasz and Vicsek. We find that there are two types of nodes: the hub and rim nodes, which form a biparti…
