DESCRIPTION:There is a function c(t) such that any graph of order n with c
 (t)n edges has a Kt minor. Improving on work of Fiorini-Joret-Theis-Wood a
 nd of Shapira-Sudakov\, we show that if the graph has (c(t)+epsilon)n edge
 s then it has a minor of order O(log n). A similar result holds for subdiv
 isions.
