Generalized Turán number for linear forests

Xiutao Zhu, Yaojun Chen

The generalized Turán number $e x (n, K_{s}, H)$ is defined to be the maximum number of copies of a complete graph $K_{s}$ in any $H$ -free graph on $n$ vertices. Let $F$ be a linear forest…

Gallai-Ramsey number of even cycles with chords

Fangfang Zhang, Zi-Xia Song, Yaojun Chen

For a graph $H$ and an integer $k \geq 1$ , the $k$ -color Ramsey number $R_{k} (H)$ is the least integer $N$ such that every $k$ -coloring of the edges of the complete graph $K_{N}$ contains…

Gallai-Ramsey number of odd cycles with chords

Fangfang Zhang, Zi-Xia Song, Yaojun Chen

A Gallai coloring is a coloring of the edges of a complete graph without rainbow triangles, and a Gallai $k$ -coloring is a Gallai coloring that uses at most $k$ colors. For an inte…
