A note on degree conditions for Ramsey goodness of trees

Zhidan Luo, Yuejian Peng

For given graphs $G_{1}, G_{2}$ and $G$ , let $G \to (G_{1}, G_{2})$ denote that each red-blue-coloring of $E (G)$ yields a red copy of $G_{1}$ or a blue copy of $G_{2}$ . Arag…

The $s$ -chromatic Ramsey number for stars

Aijun Yi, Zhidan Luo

In 1977, Chung, Chung and Liu generalized the definition of the Ramsey number. They introduced the $s$ -chromatic Ramsey number as follows. Let $1 \leq s < t$ be integers and let $A_{…

All Ramsey critical graphs for a large tree versus $t K_{m}$

Zhiyu Cheng, Zhidan Luo, Pingge Chen

Let $H, H_{1}$ and $H_{2}$ be graphs, and let $H \to (H_{1}, H_{2})$ denote that any red-blue coloring of $E (H)$ yields a red copy of $H_{1}$ or a blue copy of $H_{2}$ . The…
