Mathematics underlies the pursuit of every scientific endeavour. The Department of Mathematics within the Faculty of Science satisfies this need by contributing to joint Honours degrees with other science disciplines such as Physics, Statistics and Computer Science. Besides it also gives courses to other Faculties, like Education, Engineering, Architecture, FEMA, and ICT. The number of students taking Mathematics as a principal subject for their B.Sc.(Hons) has now stabilised at about 40 per year. Besides, about 20 students from the Faculty of Education annually follow the same Mathematics courses followed by the Mathematics students in the Faculty of Science. Student numbers in Mathematics courses for other Faculties vary greatly from faculty to faculty, with about 400 first year students in FEMA, to Engineering classes of about 200. The optional credits offered by the Mathematics Department are also very popular with students from other courses, with audiences of about 100. Part time staff are employed by the Department of Mathematics to give tutorials in Mathematics to small classes. The Department of Mathematics also offers postgraduate (Master's and Ph.D.) courses in Mathematics. Departmental research centres mainly round Graph Theory and Combinatorics, Mathematical Analysis and Mathematical Physics.
