abstract

Motivated by a conjecture from the automated conjecturing program TxGraffiti, in this paper the relationship between the zero forcing number, $Z(G)$, and the vertex independence number, $\alpha(G)$, of cubic and subcubic graphs is explored. TxGraffiti conjectures that for all connected cubic graphs $G$, that are not $K_4$, $Z(G) \leq \alpha(G) + 1$. This work uses decycling partitions of upper-embeddable graphs to show that almost all cubic graphs satisfy $Z(G) \leq \alpha(G) + 2$, provides an infinite family of cubic graphs where $Z(G) = \alpha(G) + 1$, and extends known bounds to subcubic graphs.

    math.CO 2026-07 accept novelty 7.0 of 10

    Explicit connected subcubic and cubic graphs attain Z = α + 2, refuting the TxGraffiti conjecture that Z ≤ α + 1 for connected graphs with Δ ≤ 3.

    Four machine-generated open conjectures relating independence, zero forcing, domination, and matching invariants in graphs are presented, each with empirical support but no proof.

  3. Connected forcing density and related problems

    math.CO 2025-07 conditional novelty 6.0 of 10

    A graph is CF-dense when every vertex lies in some minimum connected forcing set; the paper characterizes CF-dense trees and counts connected forcing sets in trees.
