Opis

Intends to lay a common basis for the different branches of recursion theory. Leads from the very basic theory to modern concepts of computability. Consists of three consecutive parts: 1. Basic Concepts of Computability. 2. Traditional Recursion Theory. 3. Unified Type 2 theory of constructivity and computability on Baire's space including a general the- ory of representations.
