Past Events

This is joint work with Eric Friedlander, Julia Pevtsova and Andrei Suslin. We consider modules over an elementary abelian group on which every element in the radical, but not the square of the radical, has the same Jordan canonical form. Such...

The event consists of 7 or 8 talks from algebraists, mainly from Alberta and British Columbia, and some from outside the PIMS jurisdiction. The workshop includes a banquet on the evening of April 18th, 2009.

In this talk I show that the space of almost commuting elements in a compact Lie group G splits after one suspension.

The aim of this talk is to highlight the usefulness of continuous time branching process theory in understanding refined asymptotics about various random network models. We shall exhibit their usefulness in two different contexts: (1) First passage...

Breathing is an interesting and essential life-sustaining behavior for humans and all mammals. Like many rhythmic motor behaviors, breathing movements originate due to neural rhythms that emanate from a central pattern generator (CPG) network. CPGs...

Consider the classical balls-and-bins setup: n balls are thrown independently and uniformly into n bins. The most loaded bin then has log n/log log n balls with high probability. What happens when instead of throwing balls completely by random, there...

The H^{-1}-norm appears naturally in many areas of science. For example it is used to express the electrostatic energy of a charge distribution. We study this norm on tubular neighbourhoods of curves, mainly motivated by its appearance in energy...

Schnyder showed in 1989 that every plane triangulation has a partition of its (inner) edges into 3 trees spanning all (inner) vertices. The so-called Schnyder woods are a powerful combinatorial structure with many applications: new planarity...

We consider regular geometric subdivisions. These combine the refinement of a regular lattice with a regular pattern of affine transformations applied to geometric data associated with the nodes of the lattice. Such subdivisions are used in computer...
