Irreversible Dynamos in Butterflies

We study the propagation of information in a network in the presenceof permanent faults, to detect the patterns of initial faults which may leadthe entire system to fail. Such patterns, called dynamos, have been alreadystudied in different contexts and topologies, and under different laws of faultpropagation. In our model each node assumes a new state according to themajority of the states of its neighbours. We investigate dynamos for networksof the butterfly family, estabilishing...
