Classical Recursion Theory: The Theory of Functions and Sets of Natural Numbers Volume 125

1988 marked the first centenary of Recursion Theory, since Dedekind's 1888 paper on the nature of number. Now available in paperback, this book is both a comprehensive reference for the subject and a textbook starting from first principles.

Among the subjects covered are: various equivalent approaches to effective computability and their relations with computers and programming languages
a discussion of Church's thesis
a modern solution to Post's problem
global properties of Turing degrees
and a complete algebraic characterization of many-one degrees. Included are a number of applications to logic (in particular GOdel's theorems) and to computer science, for which Recursion Theory provides the theoretical foundation.
