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 $β : V (G) \mapsto Z_{ℓ}$ with $β (v) \equiv d (v) (mod 2)$ for every vertex $v$ and $\sum_{v \in V(G)} β(v)…

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…

Planar Graphs with Homomorphisms to the 9-cycle

Daniel W. Cranston, Jiaao Li, Zhouningxin Wang +1

We study the problem of finding homomorphisms into odd cycles from planar graphs with high odd-girth. The Jaeger-Zhang conjecture states that every planar graph of odd-girth at lea…
