CT is a proposition that identifies two notions: an intuitive notion of a effectively computable function defined in natural numbers with the notion of a recursive function.

WebSep 6, 2016 · Church Turing Thesis In 1936, Alonzo Church created a method for defining functions called the λ-calculus. Within λ-calculus, he defined an encoding of the natural numbers called the Church numerals. Also in 1936, before learning of Church's work, Alan Turing created a theoretical model for machines, now called Turing machines, that could ... WebMay 5, 2015 · The theorem says that if F steps to F' in several steps, for all A, ap F A steps to ap F' A in many steps. The actual proof is quite boring, we just recurse and apply step/ap1 until everything type checks. Note that the world specification for step*/left is a little strange. We use the block lam-block because later one of our theorem needs this ...
