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…

Nowhere-zero $3$ -flow and $Z_{3}$ -connectedness in Graphs with Four Edge-disjoint Spanning Trees

Miaomiao Han, Hong-Jian Lai, Jiaao Li

Given a zero-sum function $β : V (G) \to Z_{3}$ with $\sum_{v \in V (G)} β (v) = 0$ , an orientation $D$ of $G$ with $d_{D}^{+} (v) - d_{D}^{-} (v) = β (v)$ in $Z_{3}$ for every ver…
