Welcome to Pure Mathematics

We are home to 30 faculty, four staff, approximately 60 graduate students, several research visitors, and numerous undergraduate students. We offer exciting and challenging programs leading to BMath, MMath and PhD degrees. We nurture a very active research environment and are intensely devoted to both ground-breaking research and excellent teaching.


News

More than 100 researchers and students from across Canada and around the world attended the 53rd annual Canadian Operator Algebras Symposium (COSY), which took place from May 26-30 at the University of Waterloo.

Number Theory Seminar

Stephen Melczer University of Waterloo,

Analytic Combinatorics in One and Several Variables

The field of analytic combinatorics develops effective methods to compute the asymptotic behaviour of combinatorial sequences from analytic properties of their generating functions. This talk surveys the classical methods of analytic combinatorics and details the newer area of analytic combinatorics in several variables (ACSV), which handles multivariate sequences and their multivariate generating functions. Applications to several areas of mathematics and computer science, including number theory, will be discussed. This talk will be complemented by a presentation of Erica Liu on January 27 describing some recent progress on new approaches to ACSV.

Differential Geometry Working Seminar

Spencer Kelly, University of Waterloo

Proper Group Actions and the Slice Theorem in Finite Dimensions

In this talk we will begin by reviewing important properties of group actions on manifolds, and characteristics of proper actions. We then define isotropy and orbit types, discuss the slice theorem (on finite dimensional manifolds), and go over non-trivial examples of slice bundles. This will set us up to conclude with the principal orbit theorem and the stratification of the orbit space.
