Ramsey-type results for path covers and path partitions

Shuya Chiba, Michitaka Furuya

A family of subgraphs of is called a {\it path cover} (resp. a {\it path partition}) of if (resp. $\dot\bigcup _{P\in \…

Minimum degree conditions for the existence of a sequence of cycles whose lengths differ by one or two

Shuya Chiba, Katsuhiro Ota, Tomoki Yamashita

Gao, Huo, Liu and Ma (2019) proved a result on the existence of paths connecting specified two vertices whose lengths differ by one or two. By using this result, they settled two f…

Minimum degree conditions for the existence of cycles of all lengths modulo in graphs

Shuya Chiba, Tomoki Yamashita

Thomassen, in 1983, conjectured that for a positive integer , every -connected non-bipartite graph of minimum degree at least contains cycles of all lengths modulo $k…

Partitioning a graph into cycles with a specified number of chords

Shuya Chiba, Suyun Jiang, Jin Yan

For a graph , let be the minimum degree sum of two non-adjacent vertices in . A chord of a cycle in a graph is an edge of joining two non-consecutive verti…

A degree sum condition on the order, the connectivity and the independence number for Hamiltonicity

S. Chiba, M. Furuya, K. Ozeki +2

In [Graphs Combin.~24 (2008) 469--483.], the third author and the fifth author conjectured that if is a -connected graph such that

Induced nets and Hamiltonicity of claw-free graphs

Shuya Chiba, Jun Fujisawa

The connected graph of degree sequence 3,3,3,1,1,1 is called a net, and the vertices of degree 1 in a net is called its endvertices. Broersma conjectured in 1993 that a 2-connected…
