Scaling of Clusters near Discontinuous Percolation Transitions in Hyperbolic Networks

We investigate the onset of the discontinuous percolation transition in small-world hyperbolic networks by studying the systems-size scaling of the typical largest cluster approaching the transition, $p\nearrow p_{c}$. To this end, we determine the average size of the largest cluster $\left\langle s_{\rm max}\right\rangle \sim N^{Ψ\left(p\right)}$ in the thermodynamic limit using real-space renormalization of cluster generating functions for bond and site percolation in several models of hyperbolic networks that provide exact results. We determine that all our models conform to the recently predicted behavior regarding the growth of the largest cluster, which found diverging, albeit sub-extensive, clusters spanning the system with finite probability well below $p_{c}$ and at most quadratic corrections to unity in $Ψ\left(p\right)$ for $p\nearrow p_{c}$. Our study suggest a large universality in the cluster formation on small-world hyperbolic networks and the potential for an alternative mechanism in the cluster formation dynamics at the onset of discontinuous percolation transitions.
