WebOct 21, 2024 · For this reason CT1 has come to be known as the Church-Turing Thesis. Both Church (1937b) and Kleene (1952) also note that Post (1936) independently gives an analysis very similar to Turing’s. Perhaps, then, CT1 should properly be known as the Church-Turing-Post-Thesis. http://www.people.cs.uchicago.edu/~soare/Turing/shagrir.pdf
