Popis: | A book Bp is a graph consisting of p triangles sharing a common edge. In this paper we prove that if p ≤ q/6 - o(q) and q is large, then the Ramsey number r (Bp, Bq) is given by r(Bp, Bq) = 2q + 3, and the constant 1/6 is essentially best possible. Our proof is based on Szemeredi's uniformity lemma and a stability result for books. |
