纯粹数学系是数学系五个独立的系之一。该系提供研究生课程，可攻读数学硕士学位（MMath）和哲学博士学位（PhD）。在MMath程序中
Algebra, as it is studied in modern mathematics, is the systematic generalization of arithmetic needed to model or coordinatize objects of interest to mathematicians, using numbers (or their generalizations) and natural operations on them. As the objects being modelled can be quite varied, so are the various branches of modern algebra. Discover the Master of Mathematics in Pure Mathematics program, where you’ll explore the boundary of mathematics and pure reason.With over 80 faculty, postdoctoral fellows and graduate students in the department, the breadth of research in pure mathematics is huge. This grants you the freedom to explore areas of focus that specifically resonate with you. Algebra, analysis, geometry and topology, and number theory make up the core research areas of pure mathematics, all of which can easily be applied to the real world in significant ways. Finance and cryptography are current examples of real-life applications of the field.
