The zero-forcing consequence of the minimal-forts bound

About 1 year old · traced to

Let GG be a graph, let nn be its order, and let FG\mathcal{F}_G denote the family of minimal forts of GG. Let Z⁡(G)\operatorname{Z}(G) denote the zero forcing number of GG. Zero-forcing consequence conjecture. If

∣FG∣=n/3,\lvert\mathcal{F}_G\rvert = n/3,

then

Z⁡(G)=n/3.\operatorname{Z}(G)=n/3.

The paper presents this as an observation supported by examples and by a proposition relating minimal forts, fort number, and zero forcing number; no general proof or resolution is supplied.
