Title
Large regular graphs with no induced 2K2
Abstract
Letr be a positive integer. Considerr-regular graphs in which no induced subgraph on four vertices is an independent pair of edges. The numberv of vertices in such a graph does not exceed 5r/2; this proves a conjecture of Bermond. More generally, it is conjectured that ifv>2r, then the ratiov/r must be a rational number of the form 2+1/(2k). This is proved forv/r¿21/10. The extremal graphs and many other classes of these graphs are described and characterized.
