Abstract
Many complex networks in nature have directed links; a property that affects the network's navigability and large-scale topology. Here we study the percolation properties of such directed scale-free networks with correlated in and out degree distributions. We derive a phase diagram that indicates the existence of three regimes; determined by the values of the degree exponents. In the first regime we regain the known directed percolation mean field exponents. In contrast; the second and third regimes are characterized by anomalous exponents; which we calculate analytically. In the third regime the network is resilient to random dilution; i.e.; the percolation threshold is p c →1.
