Reduction Operations and Structural Characterizations of $S^{1}$ -Flows in Graphs

Chenxing Li, Jiaao Li, Rong Luo +1

While every graph admitting a nowhere-zero $3$ -flow also admits an $S^{1}$ -flow, the converse does not hold in general as shown by Thomassen (2014). In this paper, we develop reducti…

Reconfiguration of Nowhere-zero Flows

Daniel W. Cranston, Jiaao Li, Bo Su +2

Fix an abelian group $A$ , a graph $G$ , and nowhere-zero $A$ -flows $f^{'}$ and $f^{''}$ on $G$ . Now $f^{'}$ and $f^{''}$ are \emph{ $A$ -flow-adjacent} if there exists a cycle $C$ in $G$ such tha…

Orientations of $10$ -Edge-Connected Planar Multigraphs and Applications

Daniel W. Cranston, Jiaao Li, Bo Su +2

A graph is called strongly $Z_{2 k + 1}$ -connected if for each boundary function $β : V (G) \mapsto Z_{2 k + 1}$ with $\sum_{v \in V (G)} β (v) \equiv 0 (mod 2 k + 1)$ , there exists an orientatio…

Characterization of strongly $Z_{ℓ}$ -connected graphs of small order

Jiaao Li, Bo Su, Zhouningxin Wang +1

A graph is strongly $Z_{ℓ}$ -connected if for each boundary function $I^^{2} : V (G) \mapsto Z_{ℓ}$ with $I^^{2} (v) \equiv d (v) (mod 2)$ for every vertex $v$ and $\sum_{v \in V(G)} Î²…

High-Dimensional $p$ -Normed Flows

Chenxing Li, Jiaao Li, Rong Luo +1

We generalize Tutte's integer flows and the $d$ -dimensional Euclidean flows of Mattiolo, Mazzuoccolo, RajnÃk, and Tabarelli to \emph{ $d$ -dimensional $p$ -normed nowhere-zero flows}…
