A signed interaction graph is balanced when its edge signs are consistent with a monotone structure; natural biological networks can then be compared with random networks having th…

Stability-sign conjecture. Up to replacing $\psi$ by $-\psi$, for every $x\in\mathcal{E}$,

Let a biochemical network have drift matrix $A(x_{ss})$ in its dynamics linearised about a stable steady state $x_{ss}$. A network is nearly monotone if removing some interactions…
