Subject Knowledge
Aims
This module aims to introduce and study various aspects of pure mathematics
which arise in the diverse settings of biology, chemistry, communication/IT,
to introduce some new ways of using the mathematics learned elsewhere and to
enhance the understanding of that mathematics.
Learning Outcomes
Students should know the definitions of and understand the key mathematical
concepts and their relationship to the general problems which motivate their
consideration in each of the topics of this module, that is, in the
Fibonacci sequence and its relation to population growth in mathematical
biology, in the paper folding topic to construct regular polygons, in the
graph theoretic topics motivated by the Königsberg bridge problem and the
utilities problem, and in Public Key Encryption codes.
Students should be able to explain the main proofs given in the lectures,
and be able to apply this knowledge to solve problems in number theory using
proof by induction, second order recurrence relations, elementary graph
theory, and congruence arithmetic.
Methods
Class sessions and workshops together with some handouts.
Assessment
Marked problem sheets, class test, individual project.
Subject Skills
Aims
To provide students with team working skills and develop written
communication skills and problem solving skills.
Learning Outcomes
Students will have worked in a group context to investigate a problem, draw
conclusions and make conjectures, and have written a short individual
project using library and other external resources. Students will be able to
use the techniques taught within the module to solve problems, and be able
to present arguments and solutions in a coherent and logical form.
Methods
Class sessions, workshops.
Assessment
Marked problem sheets, team work project, class test, individual project.
Explanation of Pre-requisites
Use is made of the following concepts from the modules MA1101 and MA1102:
the notion of proof in general; proof by induction; congruence arithmetic.
Course Description
The aim of this module is to introduce and study various aspects of pure
mathematics which are used in real life situations, to introduce some new
ways of using the mathematics learned elsewhere and to enhance the
understanding of that mathematics. The mathematics studied is motivated from
from a wide range of problems in biology (Fibonacci series and population
growth), communication/IT (graph theory and number theory in relation to the
travelling salesperson problem, design of electronic circuitry and public
key encryption codes), and chemistry (convex polyhedra and molecular
structure). The module is structured to encourage the mathematical qualities
of investigation, spotting patterns and making conjectures, and applying
previous knowledge to new situations through formal proofs.
Syllabus
The Fibonacci sequence and its relation to population growth in mathematical
biology, second order recurrence relations.
Paper folding to construct regular polygons, concept of an approximate
solution and convergence.
The Königsberg bridge problem and its formal setting within graph theory,
connected graphs, spanning trees, Euler circuits, Euler walks, relation to
the travelling salesperson problem.
The utilities problem as a motivation for planar graphs, Euler
characteristic of a planar graph and convex polyhedra, complete graphs,
complete bipartite graphs.
The concept of Public Key Encryption codes, Euler's totient, Euler's
theorem.
