Our regular seminar program covers a broad range of topics from applied mathematics, pure mathematics and statistics. All staff and students are welcome. This page has a complete list of past seminars and a list restricted by year can be accessed via the left-hand menu.

David Harvey - University of New South Wales
Joris van der Hoeven and I recently discovered an algorithm that computes the product of two $n$-bit integers in $O(n \log n)$ bit operations. This is asymptotically faster than all previous known...

Greg Martin - University of British Columbia
This talk is a survey of “prime number races”.  Around 1850, Chebyshev noticed that for any given value of $x$, there always seem to be more primes of the form $4n+3$ less than $x$ than there are of...

Enrico Le Donne - University of Jyvaskyla, Finland
Sub-Riemannian geometries are a generalization of Riemannian geometries. Roughly speaking, in order to measure distances in a sub-Riemannian manifold, one is allowed to only measure distances along...

Gunther Uhlmann - University of Washington
Inverse problems arise in all fields of science and technology where causes for a desired or observed effect are to be determined. By solving an inverse problem is in fact how we obtain a large part...

Terry Gannon - University of Alberta
40 years ago John Mckay noticed that 196884=196883+1, and Monstrous Moonshine was born. In 1998 Borcherds won a Fields Medal primarily for his work explaining McKay's equation. 5 years ago string...

Luc Vinet - Université de Montréal
The Bannai-Ito algebra and its relation to the Bannai-Ito polynomials will be reviewed.  Emphasis will be put on some of the connections with the Lie superalgebra $osp(1,2)$.  Centralizing elements...

Craig Tracy - University of California - Davis
The asymmetric simple exclusion process (ASEP) is arguably the simplest generalization of simple walk on the integer lattice to interacting random walkers on the integer lattice. This lecture will...

Jim Isenberg - University of Oregon
The Hawking-Penrose theorems tell us that solutions of Einstein’s equations are generally singular, in the sense of the incompleteness of causal geodesics (the paths of physical observers). These...

Johann Makowsky - Technion – Israel Institute of Technology
A. Mani and R. Stones in their paper from 2016 study the sequence of integers $tc_{a,b}(n) = T(K_n,a,b)$, where $T(G,X,Y)$ is the Tutte polynomial and $a,b \in \mathbb{Z}$. For the case $a=1$ this...

Peter Kim - University of Sydney
Human post-menopausal longevity makes us unique among primates, but how did it evolve? One explanation, the Grandmother Hypothesis, proposes that as grasslands spread in ancient Africa displacing...
