Let $G$ be a graph, and let $\mathcal{F}(G,\mathbb{Z}_2^k)$ denote the reconfiguration graph of nowhere-zero $\mathbb{Z}_2^k$-flows. A nowhere-zero $\mathbb{Z}_2^k$-flow…

Let $G$ be a graph, let $\mathbb{Z}_{4k}$ be the cyclic group of integers modulo $4k$, and let $\mathcal{F}(G,\mathbb{Z}_{4k})$ denote the reconfiguration graph of nowhere-zero…

Let $G$ be a graph, and let $\mathcal{F}(G,A)$ denote its reconfiguration graph whose vertices are nowhere-zero $A$-flows, with adjacency given by changing flow values only on a cy…
