Subject Knowledge
Aims
This module aims to free the ideas of continuity and integration from the
boring old straight line to more interesting geometric and
other mathematical objects.
Learning Outcomes
Students will see some classical examples of how a mathematical idea
developed in one context can be reworked to apply to a lot of different
situations. Explicitly, they will know the elementary stages of the study
of metric, toplogical and measure spaces and the modern theory of
integration, linked by a common flow of ideas.
Methods
Lectures, example classes, example sheets, surgeries.
Assessment
Marked problem sheets, written examination.
Subject Skills
Aims
To see how one can abstract a simple idea in one field of mathematics
and develop it to a useful tool in many others.
Learning Outcomes
Students will learn how the idea of distance on the real line is
developed to the idea of a metric on a general set, and how the study of
continuity in this setting leads to the idea of a topological space. A
similar flow of ideas leads from the inadequacy of Riemann integration to
the elementary concepts of measure theory and Lebesque integration.
Students will develop skills in presenting and understanding arguments in
an abstract setting and in the ability to construct logical arguments.
Methods
Lectures, examples classes, example sheets, surgeries.
Assessment
Marked problem sheets, written examination.
Explanation of Pre-requisites
This module takes the ideas seen in the first two analysis modules and
starts them over again in a more general and more applicable setting.
Basic familiarity with main ideas from the two earlier modules will be
assumed.
Course Description
For many thousands of years mathematicians have developed their subject
as a way to understand and describe the world around them, through
geometry, number and physical theories. Two of the main intuitive ideas
have been the concepts of measurement and proximity. Rigorous treatments
of these ideas in modern guise led to the theories of continuity and
integration seen in earlier modules, but these are inadequate in a number
of ways. For one, matheamticians deal with more things than just the real
line, and the geometry of the world (let alone of space-time or of the
quantum universe) is richer than can be found by studying just one
dimension. This module sits a a cross-roads between the classical
analysis of the real line already seen in earlier modules, and the modern
developments seen in the third and fourth level modules covering divers
topics such as Topology, Geometry, Approximation Theory, Dynamics, and so
on.
Syllabus
Metric spaces, continuity via balls and via open sets; lack of
accumulation points in an infinite set leading to ideas of completeness
and compactness. Heine-Borel and corollaries. Topological spaces and
compactness again. Sub- and quotient-spaces. Measure spaces,
-algebras and measurable functions. Lebesgue measure;
integration and Lebesgue monotone convergence theorem.
