In the language of graph theory, the Ramsey number is the minimum number of vertices, v = R(m, n), such that all undirected simple graphs of order v, contain a clique of order m, or an independent set of order n. Ramsey's theorem states that such a number exists for all m and n. By symmetry, it is true that R(m, n) = R(n, m).

78 of the 156 possible friends-strangers graphs with 6 nodes. The other 78 can be obtained by reversing the red and blue colours of each graph. For each graph the red/blue nodes shows a sample triplet of mutual friends/strangers. The theorem on friends and strangers is a mathematical theorem in an area of mathematics called Ramsey theory.
v. t. e. The Ramsey–Cass–Koopmans model, or Ramsey growth model, is a neoclassical model of economic growth based primarily on the work of Frank P. Ramsey, [1] with significant extensions by David Cass and Tjalling Koopmans. [2][3] The Ramsey–Cass–Koopmans model differs from the Solow–Swan model in that the choice of consumption is ...
