WebbHindman's theorem is named for mathematician Neil Hindman, who proved it in 1974. [4] The Milliken–Taylor theorem is a common generalisation of Hindman's theorem and Ramsey's theorem . Semigroups [ edit] Webbrestricted versions of Hindman’s Theorem are far weaker than Hindman’s Theorem itself, but in fact it is unknown whether this is true. In fact it is a major open problem in …
