On the restricted size Ramsey number for a pair of cycles

Tomasz Łuczak, Joanna Polcyn, Zahra Rahimi

For graphs $H_{1}, H_{2}$ by $r^{*} (H_{1}, H_{2})$ we denote the minimum number of edges in a graph $G$ on $r (H_{1}, H_{2})$ vertices such that $G \to (H_{1}, H_{2})$ . We show that for each pair of natur…

Stars versus stripes Ramsey numbers

G. R. Omidi, G. Raeisi, Z. Rahimi

For given simple graphs $G_{1}, G_{2}, \dots, G_{t}$ , the Ramsey number $R (G_{1}, G_{2}, \dots, G_{t})$ is the smallest positive integer $n$ such that if the edges of the complete graph $K_…
