Abstract:
Let B(k) n be the book graph which consists of n copies of Kk+1 all sharing a common Kk, and let Cm be a cycle of length m. In this paper, we first determine the exact value of r(B(2) n ,Cm) for 8 9n + 112 ≤ m ≤ ⌈ 3n 2 ⌉ + 1 and n ≥ 1000. This answers a question of Faudree, Rousseau, and Sheehan [Ars Combin., 31 (1991), pp. 239-248] in a stronger form when m and n are large. Building upon this exact result, we are able to determine the asymptotic value of r(B(k) n ,Cn) for each k ≥ 3. Namely, we prove that for each k ≥ 3, r(B(k) n ,Cn) = (k + 1 + ok(1))n. This extends a result due to Rousseau and Sheehan [J. London Math. Soc., 18 (1978), pp. 392-396]. © 2021 Society for Industrial and Applied Mathematics.
