✦ Synopsis

It is shown that there is a graph 4 with n vertices and at least n ' "edges such that it contains neither Ws nor X2 3

, but every subgraph with 2n4'3(logn)Z edges contains a vd, (n>n,). Moreover, the chromatic number of Y is at least no.'.

We consider the standard random geometric graph process in which n vertices are placed at random on the unit square and edges are sequentially added in increasing order of edge-length. For fixed k ≥ 1, we prove that the first edge in the process that creates a k-connected graph coincides a.a.s. with

As usual, for simple graphs G and H, let the Ramsey number r(G,H) be defined as the least number n such that for any graph K of order n, either G is a subgraph of K or H is a subgraph of/(. We shall establish the values of r(aC~,bCs) and r(aCv, bC7) almost precisely (where nG is the graph consisting
