Higher Recursion Theory

Since their inception the perspectives in logic and lecture notes in logic series have published seminal works by leading logicians. Many of the original books in the series have been unavailable for years but they are now in print once again. This volume the second publication in the perspectives in logic series is an almost self-contained introduction to higher recursion theory in which the reader is only assumed to know the basics of classical recursion theory. The book is divided into four parts: hyperarithmetic sets metarecursion -recursion and e-recursion. This text is essential reading for all researchers in the field.
