# Reference request - random regular graphs vs random graphs w/ degree sequence

There are some properties that are easily studied for random d-regular graphs, but that are very hard to extend to random graphs with a given degree sequence (e.g. whether a graph is w.h.p. hamiltonian).

Does anyone have any other examples of papers/problems that successfully (and not trivially) extend properties from random regular graphs to random graphs with a given degree sequence?

(I hope this is not too open ended, I am finding it hard to search online the usual way because the key words are so generic).

Simple random walk (and non-backtracking walk) on random regular graphs exhibit the cutoff phenomenon [1]. The extension to graphs with degree sequences came later; see [2] for nonbacktracking walks and [3] for simple random walk where backtrackings cause additional difficulties.

In another direction, component structure at criticality was described in a well known paper by Aldous [4]. It was adapted to random regular graphs in [5], and extended to other degree sequences in [6] and [7].
