Finally, we prove some families of graphs such as the complement of Pn, Cn with n≥3 and n = 4k, for k∈ℕ, are opposition graphs and some families of graphs such as the complement of Tn, Cn with n≥3 and n ≠ 4k, for k∈ℕ, are not opposition graphs. | 關聯: | International Journal of Discrete Mathematics, 2(3), 119-124 | 資料類型: | article | DOI: | http://dx.doi.org/10.11648/j.dmath.20170203.20 |
