An improved method for recursively computing upper bounds for two-colour Ramsey numbers

Abstract

The two-colour Ramsey number R(m,n)R(m,n) is the least natural number pp such that any graph of order pp must contain either a clique of size mm or an independent set of size nn. We exhibit a method for computing upper bounds for R(m,n)R(m,n) recursively, using known upper bounds of R(,)R(\cdot,\cdot) with lower values for at least one of the arguments. We also give an example of how this method could be used to improve several of the best known bounds that are available in the literature (which however soon will be obsolete due to a forthcoming work).
