On removable edge subsets in graphs with a nowhere-zero $4$ -flow

Davide Mattiolo

A set $R \subseteq E (G)$ of a graph $G$ is $k$ -removable if $G - R$ has a nowhere-zero $k$ -flow. We prove that every graph $G$ admitting a nowhere-zero $4$ -flow has a $3$ -removable su…

Geometric description of $d$ -dimensional flows of a graph

Davide Mattiolo, Giuseppe Mazzuoccolo, Jozef Rajník +1

A $d$ -dimensional nowhere-zero $r$ -flow on a graph $G$ , an $(r, d)$ -NZF from now on, is a flow where the value on each edge is an element of $R^{d}$ whose (Euclidean) norm li…
