*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...
