# Item Description

In a paper entitled,*On Computable Numbers, with an Application to the Entscheideungsproblem*, the author gave a proof of the insolubility of the Entscheideungsproblem of the 'engere Funktionenkalkul' This proof contained some formal errors which will be corrected here - there are also some other statements in the same paper which should have been modified, although they are not actually false as they stand' (Turing, in his first paragraph).
