A multipartite or c-partite tournament is an orientation of a complete c-partite graph. In this note we prove that a strongly connected c-partite tournament with c β₯ 3 contains an arc that belongs to a directed cycle of length m for every m β {3, 4, . . . , c}.

β¦ Synopsis
Volkmann [L. Volkmann, A remark on cycles through an arc in strongly connected multipartite tournaments, Appl. Math. Lett. 20 (2007Lett. 20 ( ) 1148Lett. 20 ( -1150] ] conjectured that a strong c-partite tournament with c β₯ 3 contains three arcs that belong to a cycle of length m for each m β {3, 4, . . . , c}. In this work, we prove that Volkmann's conjecture is true.

## Abstract A directed cycle __C__ of a digraph __D__ is extendable if there exists a directed cycle __C__β² in __D__ that contains all vertices of __C__ and an additional one. In 1989, Hendry defined a digraph __D__ to be cycle extendable if it contains a directed cycle and every nonβHamiltonian di
## Abstract An inβtournament is an oriented graph such that the negative neighborhood of every vertex induces a tournament. Let __m__β=β4 or __m__β=β5 and let __D__ be a strongly connected inβtournament of order ${{n}}\geq {{2}}{{m}}-{{2}}$ such that each arc belongs to a directed path of order at
## Abstract A set __S__ of edgeβdisjoint hamilton cycles in a graph __G__ is said to be __maximal__ if the edges in the hamilton cycles in __S__ induce a subgraph __H__ of __G__ such that __G__βββ__E__(__H__) contains no hamilton cycles. In this context, the spectrum __S__(__G__) of a graph __G__ i
It was conjectured in [Wang, to appear in The Australasian Journal of Combinatorics] that, for each integer k β₯ 2, there exists . This conjecture is also verified for k = 2, 3 in [Wang, to appear; Wang, manuscript]. In this article, we prove this conjecture to be true if n β₯ 3k, i.e., M (k) β€ 3k. W
