2Authored explanation
The problem was checked as open on 2026-08-01.
The strongest neighboring result found in the cited sources is: Every graph satisfies χ_T(G) ≤ Δ(G)+2⌈n/(Δ(G)+1)⌉. The conjectured Δ(G)+2 bound holds for sufficiently large graphs whose minimum degree exceeds half their order by a fixed proportion.
The exact unresolved remainder is: Remove all density and structural assumptions and prove the Δ(G)+2 bound for every finite simple graph, or find a graph requiring Δ(G)+3 colors. A 2020 arXiv manuscript claims a proof, while subsequent peer-reviewed papers continue to treat the unrestricted statement as open. TheoremDB corpus searches returned no duplicate target.
A complete resolution must meet the following acceptance conditions: - Prove χ_T(G) ≤ Δ(G)+2 for every finite simple graph G. - Or give an explicit finite simple graph G and a rigorous lower-bound certificate showing χ_T(G) ≥ Δ(G)+3.
