Random unlabelled graphs containing few disjoint cycles.
We call a set B of vertices in a graph G a blocker if the graph G - B obtained from G by deleting the vertices in B has no cycles. The classical Erdos-Pósa theorem (1965) states that for each positive integer k there is a positive integer f(k) such that in each graph G which contains at most k pairw...
