Abstract

We study the cover time of a random graph chosen uniformly at random from the set of graphs with vertex set [n][n] and degree sequence d=(di)i=1n\mathbf{d}=(d_i)_{i=1}^n. In a previous work, the asymptotic cover time was obtained under a number of assumptions on d\mathbf{d}, the most significant being that di3d_i\geq 3 for all ii. Here we replace this assumption by di2d_i\geq 2. As a corollary, we establish the asymptotic cover time for the 2-core of the emerging giant component of G(n,p)\mathcal{G}(n,p).
