Frustration-Critical Signed Graphs [PDF]

open access: yesDiscrete Applied Mathematics, 2022
A signed graph $(G,\Sigma)$ is a graph $G$ together with a set $\Sigma \subseteq E(G)$ of negative edges. A circuit is positive if the product of the signs of its edges is positive. A signed graph $(G,\Sigma)$ is balanced if all its circuits are positive.

Homomorphisms of Signed Graphs

Journal of Graph Theory, 2014
AbstractA signed graph is a graph G together with an assignment of signs + and − to all the edges of G where Σ is the set of negative edges. Furthermore and are considered to be equivalent if the symmetric difference of Σ1 and Σ2 is an edge cut of G. Naturally arising from matroid theory, several notions of graph theory, such as the theory of minors

On graphs with signed inverses

Networks, 1988
AbstractA graph G is called invertible if its adjacency matrix A has an inverse which is the adjacency matrix of some graph H. All such graphs were shown by Harary and Minc to have the form nK2. We now introduce signed invertible (or briefly s‐invertible) graphs G as those whose inverse H is a signed graph.
