Abstract

Let T be a Hamiltonian multipartite tournament with n vertices and γ a Hamiltonian cycle of T. We prove that for every k ,4 ≤ k ≤ n+4 , there exists a cycle C of length l(C) ∈{ k − 3 ,k − 2 ,k − 1 ,k }, whose intersection with the arcs of γ is at least l(C) − 3. In some cases the result is best possible.
