FWF - Subgraph - Supercritical behaviour in random subgraph models

Project: Research project

Project Details


Percolation, or random subgraphs, is a mathematical model originally studied in the context of statistical physics, where they model the flow of a liquid or gas through a lattice like medium whose channels are randomly blocked. For many of these models, as the density of the random subgraph increases, there is a threshold at which its likely structure changes dramatically. Below this threshold all the components are small, whereas above this threshold many of these small component coalesce and a unique large component appears. In this supercritical regime, whilst the random subgraph is still quite sparse and disconnected, its largest component displays many interesting structural properties which you would expect to appear only for much denser graphs. This project aims to investigate the structural properties of these supercritical random subgraphs, and in particular their largest components, in a range of percolation models.
