On subtournaments of a tournament
WebIt is shown that every strong in-tournament of order n with minimum indegree at least ~ is pancyclic, and digraphs that contain no multiple arcs, no loops and no cycles of length 2 are considered. An in-tournament is an oriented graph such that the in-neighborhood of every vertex induces a tournament. Therefore, in-tournaments are a generalization of local … WebThe minimum number of cycles of length k a strong tournament T can contain is n - k + 1. n This follows from Theorems 1 and 2 and the fact that each strong sub tournament T , of …

Webevery vertex v2V(T) are both transitive. Alternatively a locally transitive tournament is a tournament that has no occurrences of W 4 nor of L 4, where W 4 and L 4 are the tour-naments of size 4 with outdegree sequences (1;1;1;3) and (0;2;2;2) respectively. On the other hand, a balanced tournament is a tournament with an odd number of vertices 2n+1 Websub- + tournament Noun [ edit] subtournament ( plural subtournaments ) ( graph theory) A tournament that forms part of another tournament.
