Title: Numbers in Ramsey Theory

Abstract:  Ramsey Theory reasures us that the complete disorder is 
impossible. In graph theory setting this means that for a given a graph 
$G$ and an integer $k>1$, in any coloring of the edges of the complete 
graph $K_N$ by $k$ colors, there exists a monochromatic copy of $G$ 
provided $N$ is large. The smallest integer $N$ with this property is 
called the Ramsey number $r_k(G)$.

In the first half of my talk, we will briefly survey the most interesting 
results when $k=2$. In the second half, we look at the case when $k>2$. 
Here we do not know much even if $G$ is a very simple graph, e.g., a
