note on minimal order of a bipartite graph with exactly 4 quadrilaterals, Discrete Mathematics 121 (1993) 229-233. We show that the minimal order of a bipartite graph having exactly 4 quadrilaterals is asymptotically equal to 2fl $j (as 4 tends to infinity).

We show that an n-vertex bipartite K 3,3 -free graph with n 3 has at most 2n -4 edges and that an n-vertex bipartite K 5 -free graph with n 5 has at most 3n -9 edges. These bounds are also tight. We then use the bound on the number of edges in a K 3,3 -free graph to extend two known NC algorithms fo
