Mathematics (MAT) is a six-semester subject and Applied Mathematics (MAP) is a four-semester subject. These subjects may be taken as major subjects for the degrees of BSc, BA, BJourn, BCom, BBusSci, BEcon and BSocSc, and for the diploma HDE(SEC).

To major in Mathematics, a candidate is required to obtain credit in the following courses: MAT1; MAT 2 or MAP 2; MAT 3. See Rule S.23.

To major in Applied Mathematics, a candidate is required to obtain credit in the following courses: MAT 1, MAT 2 or MAP 2; MAP 3. See Rule S.23. The attention of students who hope to pursue careers in the field of Bioinformatics is drawn to the recommended curriculum that leads to postgraduate study in this area, in which Mathematics is a recommended co-major with Biochemistry, and for which two years of Computer Science and either Mathematics or Mathematical Statistics are prerequisites. Details of this curriculum can be found in the entry for the Department of Biochemistry, Microbiology and Biotechnology.

See the Departmental Web Page http://www.ru.ac.za/academic/departments/mathematics/ for further details, particularly on the content of courses.

First-year level courses in Mathematics

Mathematics 1 (MAT 1) is given as a year-long unsemesterized two-credit course. Credit in MAT 1 must be obtained by students who wish to major in certain subjects (such as Applied Mathematics, Physics and Mathematical Statistics) and by students registered for the BBusSci degree.

Introductory Calculus (MAT 101) is a required semester-credit course for Pharmacy students, and Discrete Mathematics (MAT 102) is a required semester-credit course for students who wish to major in Computer Science. Either or both of MAT 101 and MAT 102 may be taken for credit purposes in other degree programmes, for example by students who wish to major in Chemistry or Ichthyology. Students who have taken MAT 101 and 102 separately and who obtain a sufficiently high aggregate for the combination may be permitted to continue to second year mathematics or applied mathematics courses at the discretion of the Head of Department.

Note: Students in Pharmacy or in Computer Science will normally be obliged to register for MAT 101 or MAT 102 (respectively). However, students in Pharmacy and Computer Science have the option of taking the two-credit course MAT 1 for their degrees instead.

Supplementary examinations may be recommended for any of these courses, provided that a candidate achieves a minimum standard specified by the Department.

Mathematics 1L (MAT 1L) is a full year course for students who do not qualify for entry into any of the first courses mentioned above. This is particularly suitable for students in the Social Sciences and Biological Sciences who need to become numerate or achieve a level of mathematical literacy. A successful pass in this course will give admission to MAT 1.

Second- and Third-year level courses in Mathematics and Applied Mathematics

Both Mathematics and Applied Mathematics are offered at the second and third year level. Each consists of four topics as listed below. Two of these successfully completed in one year earn one credit in either Mathematics or Applied Mathematics at the second year level or third year level respectively. The first credit so earned will be called MAT 201 (respectively MAT 301) in the case of Mathematics, and MAP 201 (respectively MAP 301) in the case of Applied Mathematics. Subsequent credits will be MAT 202 (respectively MAT 302) and MAP 202 (respectively MAP 302). The selection of topics is subject to the approval of the Head of Department. Credit may be obtained in each semester-credit separately and, in addition, an aggregate mark of at least 50% will be deemed to be equivalent to a two-credit course MAT 2 (respectively MAT 3) or MAP 2 (respectively MAP 3), provided that a candidate obtains the required sub-minimum in each component.

Credit in Mathematics (MAT 1) is required before a student may register for MAT 201, MAT 202, MAP 201 or MAP 202. Likewise credit for MAT 2 or MAP 2 is required before admission to the third year courses.

Some of the topics below may be prerequisites for others. Not all of the eight topics might be offered in a single year.

Natural combinations are indicated in the table below. If a student chooses the two second year topics in column x, where x = 1 , 2 , 3 or 4, a natural follow-up in the 3rd year would be the topics in column x as well. However, different combinations across the columns are feasible as well. In some cases, and with the permission of the Head of Department, a third-year topic may be done in the second year and vice versa.

Columns 1 and 2 contain standard/classical mathematics which all future mathematicians should know. The topics in column 3 are particularly useful for computer scientists, and the ones in column 4 for physicists and future engineers.

Other topics may be given instead from time-to-time at third year level, depending on the student intake, e.g. Quantum Mechanics, Topology, Differential Geometry and Metric Spaces.

Mathematics and Applied Mathematics Honours

Each of the two courses consists of ten topics of about 26 lectures each, plus tutorial assignments or practical work. A Mathematics Honours course usually requires the candidate to have majored in Mathematics, whilst Applied Mathematics Honours usually requires the candidate to have majored in Applied Mathematics. The topics are selected from the following general areas covering a wide spectrum of contemporary Mathematics and Applied Mathematics:

Topology; Algebra and applications (e.g. Coding Theory and Cryptography); Mathematical Logic and Set Theory; Fuzzy Sets with applications to Topology, Algebra and Control Theory; Measure Theory and Functional Analysis; Lattice Theory; Combinatorics; Category Theory; Differential Equations; Differential Geometry; Aspects of mathematical education (such as olympiads, elementary mathematics from an advanced viewpoint); Group representations; Quantum Field Theory; Nonlinear Dynamics and Chaos Theory; Mathematics of networking; Wavelet Analysis; Numerical Analysis; Neural Networks; Information and Control; Fuzzy linear programming; Mathematical modelling.

Two or three topics from those offered at the third-year level in either Mathematics or Applied Mathematics may also be taken in the case of a student who has not done such topics before. Two or three topics may also be replaced by an appropriate project.

With the approval of the Heads of Department concerned, the course may also contain topics from Education, and from those offered by other departments in the Science Faculty such as Physics, Computer Science, and Statistics.

On the other hand, the topics above may also be considered by such Departments as possible components of their postgraduate courses.

Master's and Doctoral degrees in Mathematics or Applied Mathematics

Suitably qualified students are encouraged to proceed to these degrees under the direction of the staff of the Department. Requirements for these degrees are given in the General Rules.

A Master's degree in either Mathematics or Applied Mathematics is taken by a combination of course work and a thesis. Normally four examination papers and/or essays are required apart from the thesis. The whole course of study must be approved by the Head of Department.
