Properly colored short cycles in edge-colored graphs

Laihao Ding, Jie Hu, Guanghui Wang +1

Properly colored cycles in edge-colored graphs are closely related to directed cycles in oriented graphs. As an analogy of the well-known Caccetta-Häggkvist Conjecture, we study th…

Antimagic orientations of graphs with given independence number

Zi-Xia Song, Donglei Yang, Fangfang Zhang

Given a digraph $D$ with $m$ arcs and a bijection $τ : A (D) \to {1, 2, \dots, m}$ , we say $(D, τ)$ is an antimagic orientation of a graph $G$ if $D$ is an orientation of $…

Antimagic orientations of graphs with large maximum degree

Donglei Yang, Joshua Carlson, Andrew Owens +5

Given a digraph $D$ with $m$ arcs, a bijection $τ : A (D) \to {1, 2, \dots, m}$ is an antimagic labeling of $D$ if no two vertices in $D$ have the same vertex-sum, where t…
