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 $f^{\prime }$ and $f^{\prime \prime }$ on $G$. Now $f^{\prime }$ and $f^{\prime \prime }$ are \emph{$A$-flow-adjacent} if there exists a cycle $C$ in $G$ such tha…
