The Geometry & Topology research group at the University of Waterloo is a young and very active group. We have frequent seminars, specialized graduate courses, visitors, and postdoctoral fellows. If you are interested in graduate studies or postdoctoral fellowship opportunities in geometry and topology at Waterloo, please contact one of the group's faculty members.
Some of the research interests of our group include
- low dimensional topology
- gauge theory
- symplectic and complex geometry
- arithmetic geometry
- special holonomy and calibrations
- applications of geometry to physics
- toric geometry

Unlike for the classical Seiberg-Witten equation, the moduli space of the Seiberg-Witten equation with multiple spinors may be non-compact. The boundary in this case is modelled on the Seiberg-Witten monopoles with a singularity along a codimension two subset, which is referred to as a blow up set. The purpose of this talk is to discuss a lower bound for the 1-dimensional Hausdorff measure of the blow up set when the base manifold is of dimension three.
