Cycle double covers and non-separating cycles

Arthur Hoffmann-Ostenhof, Cun-Quan Zhang, Zhang Zhang

Which $2$ -regular subgraph $R$ of a cubic graph $G$ can be extended to a cycle double cover of $G$ ? We provide a condition which ensures that every $R$ satisfying this condition is…

Antimagic orientations of even regular graphs

Tong Li, Zi-Xia Song, Guanghui Wang +2

A labeling of a digraph $D$ with $m$ arcs is a bijection from the set of arcs of $D$ to ${1, \dots, m}$ . A labeling of $D$ is antimagic if no two vertices in $D$ have the same v…

Signed graphs: from modulo flows to integer-valued flows

Jian Cheng, You Lu, Rong Luo +1

Converting modulo flows into integer-valued flows is one of the most critical steps in the study of integer flows. Tutte and Jaeger's pioneering work shows the equivalence of modul…
