Hitting times in the binomial random graph

Abstract

Fix k2k\geq 2, choose lognn(k1)/kp1Ω(log4nn)\frac{\log n}{n^{(k-1)/k}}\leq p\leq 1-\Omega(\frac{\log^4 n}{n}), and consider GG(n,p)G\sim G(n,p). For any pair of vertices v,wV(G)v,w\in V(G), we give a simple and precise formula for the expected number of steps that a random walk on GG starting at ww needs to first arrive at vv. The formula only depends on basic structural properties of GG. This improves and extends recent results of Ottolini and Steinerberger, as well as Ottolini, who considered this problem for constant as well as for mildly vanishing pp.
