Bounds extracted by Kreisel from ineffective proofs. (English) Zbl 0896.03005

Odifreddi, Piergiorgio (ed.), Kreiseliana: about and around Georg Kreisel. Wellesley, MA: A K Peters. 289-300 (1996).
Focusing on Georg Kreisel’s contributions, the author intends to show how mathematical logic and in particular proof theory can be used to make substantial contributions to mathematics. His examples are Littlewood’s theorem of 1914, Hilbert’s Nullstellensatz (1893), Hilbert’s 17th problem (1900), \(L\)-series, and the mathematical analysis of the proofs of Roth’s theorem (1955).
For the entire collection see [Zbl 0894.03002].
