Symmetric property and edge-disjoint Hamiltonian cycles of the spined cube

Da-Wei Yang, Zihao Xu, Yan-Quan Feng +1

The spined cube $S Q_{n}$ is a variant of the hypercube $Q_{n}$ , introduced by Zhou et al. in [Information Processing Letters 111 (2011) 561-567] as an interconnection network for paral…

On oriented $m$ -semiregular representations of finite groups about valency two

Jia-Li Du, Young Soo Kwon, Da-Wei Yang

Given a group $G$ , an {\em $m$ -Cayley digraph $\G$ over $G$ } is a digraph that has a group of automorphisms isomorphic to $G$ acting semiregularly on the vertex set with $m$ orbits…

Digraph analogues for the Nine Dragon Tree Conjecture

Hui Gao, Daqing Yang

The fractional arboricity of a digraph $D$ , denoted by $γ (D)$ , is defined as $γ (D) = max_{H \subseteq D, ∣ V (H) ∣ > 1} \frac{∣ A ( H ) ∣}{∣ V ( H ) ∣ - 1}$ . Frank in [Covering branching, Acta S…
