The k-core of a graph G is the maximal subgraph ofG having minimum degree at least k. In 1996, Pittel,Spencer and Wormald found the threshold λc forthe emergence of a non-trivial k-core in the random graphG(n, λ/n), and the asymptotic size ofthe k-core above the threshold. We give a new proof of thisresult using a local coupling of the graph to a suitable branchingprocess. This proof extends to a general model of inhomogeneousrandom graphs with independence between the edges. As an example,we study the k-core in a certain power-law or 'scale-free'graph with a parameter c controlling the overall density ofedges. For each k ≥ 3, we find the threshold value ofc at which the k-core emerges, and the fraction ofvertices in the k-core when c is ε above thethreshold. In contrast to G(n, λ/n),this fraction tends to 0 as ε➝0.
