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 WebDOI: 10.1016/j.disc.2006.10.019 Corpus ID: 1425990; Almost regular c-partite tournaments contain a strong subtournament of order c when c >= 5 @article{Volkmann2008AlmostRC, title={Almost regular c-partite tournaments contain a strong subtournament of order c when c >= 5}, author={Lutz Volkmann and Stefan Winzen}, journal={Discret.
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 …
