Alan Turing Collection

Five papers published by Alan Turing in the Proceedings of the London Mathematical Society have been collected together into a single, virtual issue on Wiley Online Library.

This collection includes the paper ‘On computable numbers, with an application to the Entscheidungsproblem’ (submitted 28 May 1936, published in Proceedings of the London Mathematical Society (2) 42 (1937) 230–265), an extract of which will feature on the reverse side of the new £50 banknote, which will come into circulation in 2021.
