Frustration indices of signed subcubic graphs

Sirui Chen, Jiaao Li, Zhouningxin Wang

The frustration index of a signed graph is defined as the minimum number of negative edges among all switching-equivalent signatures. This can be regarded as a generalization of th…

Fractional balanced chromatic number of signed subcubic graphs

Xiaolan Hu, Luis Kuffner, Jiaao Li +4

A signed graph is a pair $(G, σ)$ , where $G$ is a graph and $σ : E (G) \to {-, +}$ , called signature, is an assignment of signs to the edges. Given a signed graph $(G, σ)$ wit…
