Title
A lower bound on the average degree forcing a minor
Abstract
We show that for sufficiently large d and for t >= d + 1, there is a graph G with average degree (1-epsilon)lambda t root ln d such that almost every graph H with t vertices and average degree d is not a minor of G, where lambda = 0.63817 ... is an explicitly defined constant. This generalises analogous results for complete graphs by Thomason (2001) and for general dense graphs by Myers and Thomason (2005). It also shows that an upper bound for sparse graphs by Reed and Wood (2016) is best possible up to a constant factor.
