Postgraduate Diploma in Mathematics

The postgraduate diploma course has been designed for students who want to continue their mathematics studies by delving more deeply into particular aspects of pure and applied mathematics. The modules may well be of interest to mathematically inclined scientists and engineers as well as to mathematicians.

Career relevance and employability

Mathematics is at the heart of advances in science, engineering and technology, as well as being an indispensable problem-solving and decision-making tool in many other areas of life. It is no surprise therefore that mathematics postgraduates can be found throughout industry, business and commerce, in the public and private sectors. Employers value the intellectual rigour and reasoning skills that mathematics students can acquire, their familiarity with numerical and symbolic thinking and the analytic approach to problem-solving which is their hallmark.

There are a variety of reasons for studying mathematics at postgraduate level. You may want a postgraduate qualification in order to distinguish yourself from an increasingly large graduate population. You may find, particularly if you are a professional programmer or work in finance, that your undergraduate mathematical knowledge is becoming insufficient for your career requirements, especially if you are hoping to specialise in one of the more mathematical areas, which are becoming more sought after by employers. The extent of opportunities is vast and mathematics postgraduates are equipped with skills and knowledge required for jobs in fields such as finance, education, engineering, science and business, as well as mathematics and mathematical science research.

There is more information about how OU study can improve your employability in the OU's Employability Statement from our Careers Advisory Service. You can also read or download our publication OU study and your career and look at our subject pages to find out about career opportunities.


For this postgraduate diploma you require:

120 credits from the following optional modules:

Postgraduate optional modules Credits Next start
Advanced mathematical methods (M833)

Learn advanced mathematical methods with the aid of algebraic computing language Maple, and explore various forms of approximation on this MSc in Mathematics course.

See full description.

Analytic number theory I (M823)

This course introduces number theory - which is still undergoing intensive development - using techniques from analysis, particularly the convergence of series and the calculus of residues.

See full description.

30 Feb FINAL
Analytic number theory II (M829)

This course teaches number theory using techniques from analysis, and in particular the convergence of series and the calculus of residues.

See full description.

30 Feb FINAL
Applied complex variables (M828)

Complex variable theory pervades many subjects, and this course teaches topics that are useful in the theoretical sciences and of interest in their own right.

See full description.

30 Feb
Approximation theory (M832)

Develop your understanding of the mathematical theory behind many approximation methods in common use. The course is based on M.J.D. Powell's Approximation Theory and Methods.

See full description.

30 Feb FINAL
Calculus of variations and advanced calculus (M820)

This course, which develops the theory of the calculus of variations and other related topics, is the starting point for our MSC in Mathematics.

See full description.

30 Feb
Coding theory (M836)

Explore the theory of error-detecting and error-correcting codes, investigate the bounds of these codes, and discover how they can be used in real situations.

See full description.

30 Feb
Fractal geometry (M835)

This course examines the theory of fractals - whose geometry cannot easily be described in classical terms - and studies examples to which it can be applied.

See full description.

Functional analysis (M826)

This course, based on Elements of Functional Analysis by I.J. Maddox, examines sets of functions, and looks at mapping from one set to others.

See full description.

Nonlinear ordinary differential equations (M821)

Relevant to scientists, engineers and mathematicians, this introduction to basic theory and simpler approximation schemes covers systems with two degrees of freedom.

See full description.
