Classical Recursion Theory: The Theory of Functions and Sets by Piergiorgio Odifreddi

By Piergiorgio Odifreddi

1988 marked the 1st centenary of Recursion idea, due to the fact that Dedekind's 1888 paper at the nature of quantity. Now on hand in paperback, this ebook is either a complete reference for the topic and a textbook ranging from first principles.

Among the themes lined are: a variety of similar methods to potent computability and their kinfolk with desktops and programming languages; a dialogue of Church's thesis; a contemporary way to Post's challenge; international homes of Turing levels; and an entire algebraic characterization of many-one levels. integrated are a few functions to common sense (in specific Gödel's theorems) and to computing device technological know-how, for which Recursion thought offers the theoretical origin.
