We establish rates of convergence of solutions to scaling (or similarity) profiles in a coagulation type system modelling submonolayer deposition. We prove that, although all memory of the initial condition is lost in the similarity limit...

Broad area Quantum Cascade Lasers (BA-QCLs) tend to oscillate on fewer transverse modes than the number which can be supported by the waveguide. In cases lasing is dominantly if not totally on a single high-order transverse mode, it leads to a well...

The ABC Algebra Workshop is a series of one or two day workshops, featuring invited algebraists, from Alberta and British Columbia, and others from outside of Canada. Location: University of Alberta, Central Academic Building, Room 657. Click here...

In this talk, I will present my recent result about the ergodic properties of nonequilibrium steady-state (NESS) for a stochastic energy exchange model. The energy exchange model can be seen as a stochastic approximation of a certain billiards-like...

Entropy is one of the most important invariants in dynamical systems, in both measure-theoretic and topological settings. The original Kolmogorov-Sinai entropy was introduced for integer group actions in the late 1950s and extended to amenable group...

Stratified shear flows are ubiquitous features of the ocean and atmosphere, and a large literature is devoted to describing their stability and mixing properties. A classical results is the Miles-Howard theorem, which states that a necessary...

We invite our graduate students to the Palisades Centre in beautiful Jasper National Park. We offer a series of scientific and professional development activities, where we discuss mathematical modelling of biological problems, analysis of partial...

The Alberta Mathematics Dialogue (AMD) emerged naturally from the Alberta Colleges Mathematics Conference (ACMC) and the North-South Dialogue (NSD). The first North-South Dialogue took place eighteen years ago, and 2019 will be the sixth Alberta...

We propose, analyze and test Anderson-accelerated Picard iterations for solving the incompressible Navier-Stokes equations (NSE). Anderson acceleration has recently gained interest as a strategy to accelerate linear and nonlinear iterations, based on...

Ordinal outcomes are common in scientific research and everyday practice, and we often rely on regression models to make inference. A long-standing problem with such regression analyses is the lack of effective diagnostic tools for validating model...
