Antidirected hamiltonian paths in $k$ -hypertournaments

Hong Yang, Changchang Dong, Jixiang Meng +1

A $k$ -hypertournament $H$ on $n$ vertices is a pair $(V (H), A (H))$ , where $V (H)$ is a set of vertices and $A (H)$ is a set of $k$ -tuples of vertices, called arcs, such that for any $…

Sufficient conditions for closed-trailable in digraphs

Changchang Dong, Hong Yang, Jixiang Meng +1

A digraph $D$ with a subset $S$ of $V (D)$ is called $S$ {\bf -strong} if for every pair of distinct vertices $u$ and $v$ of $S$ , there is a $(u, v)$ -dipath and a $(v, u…
