Module summarySet theory is generally accepted as a foundation for mathematics, in an informal sense. It is also a formal axiomatic system, as developed by Zermelo and Fraenkel, among others, building on work of Cantor. Model theory is the study of formal axiomatic systems in full generality, and also depends on set theory for many of its basic definitions and results. Model theory and set theory constitute two of the basic strands of mathematical logic. They present rather special ways of viewing different parts of mathematics from a common perspective. In this module we explain the basic notions of these interrelated subjects.
ObjectivesTo present both informal and axiomatic set theory as a foundation for mathematics. To develop the theory of ordinals and cardinals including arithmetical operations, and to introduce some basic number systems via set theory. To convey the notions of first-order structures, and of interpretations of a formula in a structure. To describe the compactness theorems of first order logic, and some of its consequences. To introduce basic notions associated with complete theories. To consider applications of both set theory and model theory.
On completion of this module, students should be able to:
a) test various abstraction terms for sethood;
b) use set theory to set up a foundation for mathematics, including constructions of some basic number systems.
c) handle elementary arguments involving ordinals and cardinals;
d) understand the axiom of choice;
e) describe the relationships between first order languages and structures, and understand the proof of the compactness theorem of first order logic;
f) describe definable sets in structures, recognizing how this depends on the language chosen;
g) apply the compactness theorem, as well as tests for completeness.
We will start with a naive approach to set theory, giving the basic definitions and results around well-orderings, ordinals, cardinals, transfinite induction, and the axiom of choice. This includes ordinal and cardinal arithmetic (which is an arithmetic of “infinite” numbers in various senses). We will then cover
- first order languages, structures, and theories
- the compactness theorem of first order logic
- the Lowenheim Skolem theorems, elementary equivalence, and complete theories.
- set theory as a first order theory.
