WebJan 1, 2024 · Meanwhile, cubic Halin graph was studied by the authors in [9] and [2] independently. Theorem 1.8 [2], [9] If H is a cubic Halin graph, then χ star ′ (H) ≤ 6. Furthermore, the bound is tight. Hu et al. [10] proved that if H is a Halin graph with maximum degree Δ ≥ 4, then the strong chromatic index is at most 2 Δ + 1.
