The diagonal Ramsey number r(n, n) is defined [5, p. 16] as the smallest p such that in any 2-coloring of the complete graph K2,, there always occurs a monochromatic Kn. Generalizing this concept, we now define the Ramsey number r(F) for any graph F with no isolated points. The value of r(F) is the smallest p such
