- Learning Outcomes
- On successful completion of this module students will be able to
- Construct very simple Turing machine programs.
- Construct proofs of formulae in propositional and first-order logic, including resolution, the Deduction Theorem, and derived rules.
- Determine the solvability or otherwise of various computational problems.
- Extend their knowledge of mathematical logic or proceed to further study of the subject.
- Module Content
-
- Turing machines, universal Turing machine, halting problem, recursion (fixpoint) theorem, recursive separability, (total) recursive functions are not even semidecidable.
- Propositional logic, resolution, Frege's axioms I--III, deduction theorem, completeness.
- First-order theories, axioms IV, V models, skolem forms, Herband's Theorem, completeness of first-order logic.
- Peano Arithmetic, representability of arithmetic functions, Gödel's first incompleteness theorem, Tarksi, and Church, as regards computability. Gödel's Theorem, original version.
- Consistency: Hilbert-Bernays derivability conditions I--III, deduction of Goedel's second incompleteness theorem. Another view: consistency related to recursiveness.
- Module Prerequisite
- None beyond SF level modules.
- Assessment Detail
-
2-hour examination in December 2018, counting for 80%. Fortnightly quizzes will count for 20%. .
