Equitable induced-forest partition conjecture for bounded-degree graphs

Let GG be a graph with maximum degree Δ\Delta. An equitable partition is a partition of the vertex set into parts whose sizes differ by at most one, and an induced forest is a vertex-induced subgraph that is a forest. Equitable induced-forest partition conjecture. For any integers Δ\Delta and kΔ+12k\geqslant\left\lceil\frac{\Delta+1}{2}\right\rceil, every graph of maximum degree Δ\Delta can be equitably partitioned into kk induced forests. The provided excerpt does not state whether this conjecture has been resolved, so its status remains open here.
