Ramsey goodness of fans

Yanbo Zhang, Yaojun Chen

Given two graphs $G_{1}$ and $G_{2}$ , the Ramsey number $r (G_{1}, G_{2})$ refers to the smallest positive integer $N$ such that any graph $G$ with $N$ vertices contains $G_{1}$ as a subgraph,…

Proof of a Conjecture on Online Ramsey Numbers of Paths

Yanbo Zhang, Yixin Zhang

For two graphs $G_{1}$ and $G_{2}$ , the online Ramsey number $r ~ (G_{1}, G_{2})$ is the smallest number of edges that Builder draws on an infinite empty graph to guarantee that there…

Proof of a Conjecture on Online Ramsey Numbers of Stars versus Paths

Ruyu Song, Sha Wang, Yanbo Zhang

Given two graphs $G$ and $H$ , the online Ramsey number $r ~ (G, H)$ is defined to be the minimum number of rounds that Builder can always guarantee a win in the following $(G,…
