A -decomposition of the -fold line graph of

Yifan Zhao, Yulong Wei, Weihua Yang

The small cycle decompositions of line graph (-fold line graph) of complete graphs and complete bipartite graphs are studied by many papers. In particular, Colby and Rodger obta…

Planar graphs without cycles of length from 4 to 7 are near-bipartite

Lili Hao, Weihua Yang, Shuang Zhao

A graph is near-bipartite if its vertex set can be partitioned into an independent set and a set which induces a forest. In this paper, planar graphs without cycles of length from…

On the regular 2-connected 2-path Hamiltonian graphs

Xia Li, Weihua Yang

A graph is -path Hamiltonian if every path of length not exceeding is contained in a Hamiltonian cycle. It is well known that a 2-connected, -regular graph on at…

A note on -free graphs and -free graphs

Wenjian Jia, Shuai Kou, Chengfu Qin +1

Let and be the planar and non-planar graphs that obtained from the Octahedron by 3-splitting a vertex respectively. For , we prove that a 4…

On traceable iterated line graph and hamiltonian path index

Zhaohong Nou, Liming Xiong, Weihua Yang

Xiong and Liu [L. Xiong and Z. Liu, Hamiltonian iterated line graphs, Discrete Math. 256 (2002) 407-422] gave a characterization of the graphs for which the -th iterated lin…
