This talk will discuss results in a joint paper of mine with Steve Lalley from 1992. Suppose a particle, starting at position 0, moves according to a diffusion process on the real line. Suppose also that this particle emits daughter particles...

Classifying solutions is one of central themes in nonlinear partial differential equations. This is the content of various Liouville type theorems and more recently De Giorgi type conjectures. I will report recent progress towards De Giorgi's...

The consensus problem plays a central role in the theory of distributed computing. I will prove that consensus is impossible to solve in some asynchronous shared memory systems and I will present some algorithms for solving it in others, together...

The field of Mathematical Biology has experienced a rapid development in the last decade. Current mathematical tools are approaching a level of sophistication that allows for a high-level application of these techniques to real biological problems...

A video of this event is available on mathtube.org Modern symbolic computation systems provide an expressive language for describing mathematical objects. For example, we can easily enter equations such asf=x^{2^{100}}y^2 + 2x^{2^{99}+1}y^{2^{99}+1}...

The purpose of this two-day meeting is to bring together researchers in discrete mathematics from across the prairies and neighbouring provinces and states. The topics of the meeting will be areas of discrete mathematics including graph theory...

This is a two-day workshop with many talks by graduate students and selected talks by invited experts. Topics for this workshop include graph theory, finite geometries, designs, and extremal combinatorics.

A video of this event is available on mathtube.org. Statistical science has a 200-year history of advances in theory and application. Data science is a relatively newly defined area of enquiry deriving from big data. The interplay between them, and...

A video of this event is available on mathtube.org. This will be a general talk about the role of dilation theory in studying operators on Hilbert space, illustrated in part by some recent work of mine with Raphaël Clouâtre on multivariable operator...

The geodesics on a sphere (the prototypical positively curved surface) are the great circles, all of which are closed (that is, each great circle eventually returns to its initial point, in the same direction as it left). It is a remarkable fact that...
