A graph minors characterization of signed graphs whose signed Colin de Verdière parameter $ν$ is two

Marina Arav, Frank J. Hall, Zhongshan Li +1

A signed graph is a pair $(G, Σ)$ , where $G = (V, E)$ is a graph (in which parallel edges are permitted, but loops are not) with $V = {1, ..., n}$ and $Σ \subseteq E$ . The edges in $Σ$ ar…

The inertia set of a signed graph

A signed graph is a pair $(G, Σ)$ , where $G = (V, E)$ is a graph (in which parallel edges are permitted, but loops are not) with $V = 1, ..., n$ and $Σ \subseteq E$ . By $S (G, Σ)$ we denote…
