Module summaryMetamathematics and proof theory try to answer fundamental questions about axiomatic theories (e.g. number theory) like: - Are they consistent (free from contradiction)?- How do we know?- Could they be developed by computers without human assistance?- Are mathematicians necessary? The main goal is to prove Gödel's Incompleteness Theorems (1931) which show that if a formal theory has strong enough axioms then there are statements which it can neither prove nor refute. This module will also provide background to the impact of Gödel's Theorem on the modern world, and the way it sets an agenda for further research.
ObjectivesOn completion of this module, students should be able to:
a) carry out elementary proofs in systems of arithmetic;
b) prove representability and recursiveness of basic number-theoretic functions and relations;
c) understand and reproduce proofs of Gödel's Incompleteness Theorem and related results;
d) describe connections between incompleteness, consistency, computability and undecidability;
e) show a capacity for independent thinking, including further development of the theory via a range of more challenging homework problems.
a) An understanding of basic systems of arithmetic;
b) an understanding of the notions of compubtability, recursive enumerability and representability;
c) A knowledge of Gödel's Incompleteness Theorem, its proof and implications.
Understanding how a basic computing device works and can be programmed
How to show unprovability results
- Revision of first-order logic including Gödel's Completeness Theorem;
- The axiomatic method and basic systems of arithmetic;
- register machines;
- recursive functions and representability;
- the arithmetization of syntax and Gödel's First Incompleteness Theorem;
- consistency, undecidability and computability;
- Further topics from amongst the following: Second Incompleteness Theorem, Löb's Theorem, relative computation and Turing degrees.
