The $m$ -bipartite Ramsey number of the $K_{2, 2}$ versus $K_{6, 6}$

Yaser Rowshan

Given bipartite graphs $G_{1}, \dots, G_{n}$ , the bipartite Ramsey number $B R (G_{1}, \dots, G_{n})$ is the last integer $b$ such that any complete bipartite graph $K_{b, b}$ with edges col…

The $m$ -bipartite Ramsey number $B R_{m} (H_{1}, H_{2})$

Yaser Rowshan

In a $(G^{1}, G^{2})$ coloring of a graph $G$ , every edge of $G$ is in $G^{1}$ or $G^{2}$ . For two bipartite graphs $H_{1}$ and $H_{2}$ , the bipartite Ramsey number $B R (H_{1}, H_{2})$ is the least…

Another view of Bipartite Ramsey numbers

Yaser Rowshan, Mostafa Gholami

For bipartite graphs $G$ and $H$ and a positive integer $m$ , the $m$ -bipartite Ramsey number $B R_{m} (G, H)$ of $G$ and $H$ is the smallest integer $n$ , such that every red-blue color…

Extremal results on $G$ -free colorings of graphs

Yaser Rowshan

Let $H = (V (H), E (H))$ be a graph. A $k$ -coloring of $H$ is a mapping $π : V (H) ⟶ {1, 2, \dots, k}$ so that each color class induces a $K_{2}$ -free subgraph. For a graph $…

On generalized list $\G$-free colorings of graphs

Yaser Rowshan

For given graph $H$ and graphical property $P$ , the conditional chromatic number $χ (H, P)$ of $H$ , is the smallest number $k$ , so that $V (H)$ can be decomposed into sets $V_1,V_2,\l…

Multipartite Ramsey number $m_{j} (K_{m}, n K_{2})$

Yaser Rowshan

Assume that $K_{j \times n}$ be a complete, multipartite graph consisting of $j$ partite sets and $n$ vertices in each partite set. For given graphs $G_{1}, G_{2}, \dots, G_{n}$ , the mult…
