Module summary
The abstract notion of Turing machine anticipated today's real-life computers, while the intrinsic limitations of computers were dramatically spotlighted by Gödel's theorem and the notion of a 'universal' Turing machine. This module gives an introduction to the novel concepts and powerful techniques of modern computability theory, and touches on some of the major research questions concerning the structure of the computable and non-computable universe, and the relevance of pure mathematics to computer science. This is a challenging course and should only be attempted by students with a strong background in Pure Mathematics.Objectives
On completion of this module, students should be able to:a) prove basic theorems on computable functions and computably enumerable sets;
b) construct recursive definitions and verify properties of them;
c) recognise different types of recursively enumerable sets;
d) carry out basic degree theoretic constructions.
e) appreciate the significance of Post's Theorem about the arithmetical hierarchy.
Syllabus
Turing machines, computable functions and their indexing, recursive programs and recursive functions, equivalence of computability with recursiveness, computably enumerable sets and undecidable problems, creative sets and simple sets, relationships with logic and complexity theory, oracle computations and relative computability, the degrees of unsolvability, the jump operator, 1-generic sets and applications, finite injury priority methods and the Friedberg-Muchnik theorem. Computing with oracles. The arithmetical hierarchy. Post's Theorem. Forcing and category.
