The classical theorem of Edouard Helly (1913) is a masterpiece of geometry. In the simplest form it states that if a family $\Gamma$ of convex sets in $R^n$ has the property that every $n+1$ of the sets have a non-empty intersection, then all the...

Mathematical models of wind turbine blade aerodynamics have provided valuable limits on the performance for actual wind turbines. The simplest and best known is the Betz limit on power production. It is less well-known that this limit applies only at...

It is typically used to study evolutionary scenarios in low-dimensional phenotype spaces, such as the important phenomenon of evolutionary branching (adaptive diversification). I will briefly recall the basic theory of evolutionary branching and...

Dennis Gabor was a Hungarian/British physicist who invented holography, for which he received the 1971 Nobel Prize. However, in the world of seismic data analysis, he is best known for the Gabor transform, a special case of the short-time Fourier...

A video of this event is available on mathtube.org. Wavelets have been successfully applied to many areas. For high-dimensional problems such as image/video processing, separable wavelets are widely used but are known to have some shortcomings such...

Many studies have shown that the most important factor in investment success is asset allocation, as opposed to stock picking. At its most basic level, this amounts to the choice of how much to allocate to bonds and stocks.In this talk, I will...

The University of Calgary Biostatistics Centre (UCBC), a centre within the O'Brien Institute for Public Health, is hosting a day-long event on data visualization. Data visualization shows patterns and complex relationships in data. It is a critical...

In the history of philosophy, much has been made of the disagreements between W. V. O. Quine and Rudolf Carnap on the nature of mathematical and scientific knowledge. But when the dust settles, the points of agreement are more substantial...

In quantum mechanics d-partite systems are presented by d-mode tensors.Unentangled states are rank one tensors. Entangled states can be characterized their rank > 1, their spectral norm 1 or their nuclear norm > 1. In this talk I will discuss...

I will describe recent joint work with Jeroen Sijsling, Drew Sutherland, John Voight and Dan Yasaki on genus 2 curves over Q. Our work has three primary goals: (1) produce an extensive table of genus 2 curves and their associated invariants; (2)...
