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

A correction to the Zero Forcing Number of the Generalized Petersen Graphs $P (n, 3)$

Arnav Krishnan

Rashidi, Shajareh Poursalavati, and Tavakkoli [J. Algebra Comb. Discrete Struct. Appl. 7 (2020), no.2, 183-193, Theorem 3.6] claim $Z (P (n, 3)) = 8$ for all $n \geq 12$ , but this fai…
