colors‚ red and blue‚ it is impossible to color the edges of the kn without forming either a red kp or a blue kq. In short we formulate it as kn[pic]kp‚kq (read as kn arrows kp‚kq). The smallest value of such n is denoted by r(p‚q)‚known as the Ramsey number. A famous example for the two color Ramsey theorem is k6 which arrows k3‚k3. To prove k6 [pic]k3‚k3‚ let’s put 6 points on a plane and call one of them v. There are 5 edges joining v to the remaining 5 points. Let’s color them red
