### Pre-requisite qualifications

Familiarity with proof by mathematical induction.

Interest in abstract, mathematical proof writing.

### This module is mutually exclusive with

 PHIL2122 Formal Logic

This module is approved as a discovery module

### Module summary

This module is an introduction to mathematical logic introducing formal languages that can be used to express mathematical ideas and arguments. It throws light on mathematics itself, because it can be applied to problems in philosophy, linguistics, computer science and other areas.

### Objectives

- To describe the fundamental notions of mathematical logic, including the distinction between syntax and semantics.
- To present a proof of the completeness theorem in the propositional case and introduce a first order predicate calculus.

On completion of this module, students should be able to:
(a) express logical arguments in a formal language, and thereby to analyse their correctness;
(b) find disjunctive normal form for a propositional formula and prenex normal form for a first order formula
(c) distinguish between syntax and semantics, and give simple formal proofs in a natural deduction system.

### Syllabus

1. Some basic set theory (possibly including functions, relations, possibly orderings, Countable/uncountable sets, possibly Boolean algebras)
2. Propositional Logic. Syntax. Semantics. Satisfiability, tautologies, contradictions, tautologies. Disjunctive and conjunctive normal forms. A formal proof system. Completeness and (possibly) compactness.
3. Predicate Logic. Language and syntax. First-order structures. Truth in a structure. Possibly prenex normal form. A formal proof system.
