chromatic uniqueness of Certain Complete Tripartite Graphs
收藏 引用
Acta Mathematica Sinica,English Series 2011年 第5期27卷 919-926页
作者: G. C. LAU Y. H. PENG Faculty of Computer & Mathematical Sciences Universiti Teknologi MARA (Segamat Campus) 85100 Segamat Johor Malaysia Department of Mathematics and Institute for Mathematical Research Universiti Putra Malaysia 43400 UPM Serdang Malaysia
Let P(G,A) be the chromatic polynomial of a graph G. A graph G is chromatically unique if for any graph H, P(H, λ) = P(G, λ) implies H is isomorphic to G. Liu et al. [Liu, R. Y., Zhao, H. X., Ye, C. F.: A com... 详细信息

A Note on chromatic uniqueness of Completely Tripartite Graphs
收藏 引用
Journal of Mathematical Research and Exposition 2010年 第2期30卷 233-240页
作者: Ke Yi SU Xiang En CHEN College of Mathematics and Information Science Northwest Normal University Gansu 730070 P. R. China
Let P(G,λ) be the chromatic polynomial of a simple graph G. A graph G is chromatically unique if for any simple graph H, P(H,λ) = P(G,λ) implies that H is isomorphic to G. Many sufficient conditions guarantee... 详细信息

chromatic uniqueness of the Complement of T_m(l, 4, m - 6)
收藏 引用
Chinese Quarterly Journal of Mathematics 2004年 第2期19卷 133-141页
作者: ZHANGShu-min DepartmentofMathematics QinghaiNormalUniversityXining810008China
In the paper, we prove that the complement of Tm(1,4,m-6)(m> 10) is chromatically unique if and only if m≠5k(k≥2).

chromaticity of Complete 6-Partite Graphs with Certain Star or Matching Deleted Ⅱ
收藏 引用
Acta Mathematicae Applicatae Sinica 2013年 第1期29卷 35-42页
作者: Roslan Hasni Ameen Shaman Ameen Yee-Hock Peng Hai-xing Zhao School of Mathematical Sciences Universiti Sains Malaysia Department of Mathematics and Institute for Mathematical Research University Putra Malaysia Department of Mathematics Qinghai Normal University
Let P(G, λ) be the chromatic polynomial of a graph G. Two graphs G and H are said to be chromatically equivalent, denoted G N H, if P(G, λ) = P(H, λ). We write [G] = {HIH - G}. If [G] = {G}, then G is said to... 详细信息
