Webb7 juli 2024 · University of Lethbridge. Ramsey theory takes its name from Frank P. Ramsey, a British mathematician who died in 1930 at the tragically young age of 26, when he developed jaundice after an operation. Ramsey was a logician. A result that he considered a minor lemma in one of his logic papers now bears the name “Ramsey’s Theorem” and … Ramsey theory, named after the British mathematician and philosopher Frank P. Ramsey, is a branch of mathematics that focuses on the appearance of order in a substructure given a structure of a known size.

WebbR(s, t) = R(t, s) since the colour of each edge can be swapped. Two simple results are R(s, 1) = 1 and R(s, 2) = s. R(s, 1) = 1 is trivial since K1 has no edges and so no edges to colour, thus any colouring of K1 will always contain a blue K1. R(s, 2) = s is also a simple result; if all the edges of Ks are coloured red, it will contain a red Ks ...
