BL An introduction to the topic - pitched at an elementary level This Oxford Logic Guide presents a unified treatment of fixed points, self-reference, and diagonalization as they occur in Goedel's incompleteness proofs, recursion theory, combinatory logics, semantics, and metamathematics. There is also a presentation of new results - partly in these areas, but mostly in their synthesis.

In 1931, Princeton mathematician Kurt Godel startled the scientific world with his 'Theorem of Undecidability', which showed that some statements in mathematics are inherently 'undecidable'. This volume of the 'Oxford Logic Guides' is a sequel to Smullyan's Godel's 'Incompleteness Theorems' (Oxford Logic Guides No. 19, 1992).
