PMA Level 2 Modules

PMA2002 Analysis (1st semester) Core Module
Prerequisite: MTH1001 and MTH1002
Lecturer: Dr B McMasterIntroduction
This module extends and develops five of the key ideas from MTH1001, namely convergence of sequences and of series, and continuity, differentiation and integration of real functions.
Contents
Cauchy sequences, especially their characterisation of convergence. Infinite series: further convergence tests (limit comparison, integral test), absolute convergence and conditional convergence, the effects of bracketing and rearrangement, the Cauchy product, key facts about power series (longer proofs omitted). Uniform continuity: the twosequence lemma, preservation of Cauchyness (and the partial converse on bounded domains), equivalence with continuity on closed bounded domains, a gluing lemma, the bounded derivative test. Mean value theorems including that of Cauchy, proof of L'Hôpital's rule, Taylor's theorem with remainder. Riemann integration: definition and study of the main properties, including the fundamental theorem of calculus.Assessment

PMA2008 Group Theory (2nd semester)
Prerequisite: MTH1002
Lecturer: Prof I TodorovIntroduction
Consider the symmetries of a square. It has four rotations: by π/2, πi, 3πi/2 and 2πi, which is the identity transformation! It has four reflections: horizontal, vertical and two diagonals. Any combination of these symmetries is another such symmetry and each symmetry has an inverse that undoes the transformation. This is an example of a group, a mathematical abstraction of a collection of symmetries of an object.
Another example of a group is the set of bijections of the numbers 1 to n. This group is called the symmetric group on n letters, it is fundamental to the study of groups and was one of the earliest studied examples. Permutation groups are used throughout mathematics and were used in the search for a general formula for the roots of a polynomial. They can also be used to describe card shuffles.
Overall, group theory (along with linear algebra) is the basis of abstract algebra, a central theme of both pure and applied mathematics.
