Sharp zero forcing numbers for the generalized Petersen graphs $P(n,3)$ and $P(n,4)$

Arnav Krishnan, Haobo Ma, Wenlin Zhang

We prove that $Z(P(n,3))=8$ for every $n\ge 13$ and $Z(P(n,4))=10$ for every $n\ge 18$, with both stabilization thresholds sharp, and give the exact values for all smaller admissible…
