The Mathematical and Computational Sciences at Western are represented by four separate departments: Applied Mathematics, Computer Science, Mathematics, and Statistical & Actuarial Sciences. The Department of Mathematics has established research groups in several areas of contemporary mathematics including algebra, analysis and analytic geometry, homotopy theory, and noncommutative geometry.

Each week the Department of Mathematics hosts a wide variety of seminars and events. For a comprehensive list of events, please consult our departmental calendar.

Ricci-flat spaces are analogues of space-times satisfying Einstein's vacuum field equations of General Relativity. Unlike their flat cousins, these spaces exhibit fascinating geometric properties and are poorly understood. In odd dimensions the only non-trivial Ricci-flat spaces we can find are 7-dimensional and they appear in theoretical physics, making geometry in 7 dimensions particularly compelling to study. I will describe in an elementary way some of the recent endeavours to understand this geometry and several key open questions.
