Almost regular c-partite tournaments contain a strong subtournament of order c when c≥5
Lutz Volkmann,Stefan Winzen +1 more
TL;DR: The conjecture that D contains a strongly connected subtournament of order p for every [email protected]?{3,4,...,c-1} and he conjectured that this also holds for p=c, if c>=5 is settled in affirmative.
Journal ArticleDOI
Complementary cycles in regular multipartite tournaments, where one cycle has length five
TL;DR: It is demonstrated that Yeo's conjecture is not true in general for regular 4-partite tournaments with two vertices in each partite, but in all other cases it will be confirmed in affirmative.
Cycles through a given arc in almost regular multipartite tournaments.
Lutz Volkmann,Stefan Winzen +1 more
TL;DR: All digraphs are finite without loops and multiple arcs and this theorem is extended to all almost regular c-partite tournaments with c ≥ 7 such that there are at least two vertices in each partite set.
Restricted arc-connectivity of generalized tournaments
TL;DR: All strongly connected tournaments, multipartite tournaments, local tournaments and in-tournaments, and the k-restricted arc-connectivity S, defined as the minimum cardinality over all restricted arc-cuts S, are characterized.
