Multi-agent consensus over time-invariant and time-varying signed digraphs via eventual positivity
Angela Fontan, Lingfei Wang, Yiguang Hong +2
Laplacian dynamics on signed digraphs have a richer behavior than those on nonnegative digraphs. In particular, for the so-called "repelling" signed Laplacians, the marginal stabil…
