Detection of Modules in Boolean Networks — •Matthias Rybarsch und Stefan Bornholdt — Institut für Theoretische Physik

We investigate methods for detecting modules in Boolean networks. In particular, we study a damage spreading perspective on modular organization in Boolean networks and relate this to criticality in these systems. We find that the modular organization of a network is sensitively dependent on the dynamical regime of the network. We characterize quantities as the number of resulting modules, as well as the distribution of module sizes in the different regimes of the network. Finally we discuss possible implications for biological systems where these networks are used as models.
