The talk is aimed at a general academic mathematical audience, so should be suitable for graduate students, post-docs, and faculty. The set of solutions to a diophantine equation is strongly influenced by the geometry of the associated algebraic...

An automorphism of a Cayley graph that preserves its natural edge-colouring is called colour-preserving. We study groups G with the property that every automorphism on every connected Cayley graph on G is the composition of a left-translation and a...

Thin sheets exhibit a daunting array of patterns. A key difficulty in their analysis is that while we have many examples, we have no classification of the possible "patterns." I have explored an alternative viewpoint in a series of recent projects...

The vast majority of organisms, because of their small size, live in a regime where their inertia is negligible. Familiar strategies for locomotion through fluids, such as imparting momentum onto the surrounding medium, are ineffective at this scale...

Bayesian inference provides a natural framework for quantifying uncertainty in model parameters and predictions, and for combining heterogeneous sources of information. But the computational demands of the Bayesian framework constitute a major...

Let L be a positive definite lattice. There are only finitely many positive definite lattices L' which are isomorphic to L modulo N for every N > 0: in fact, there is a formula for the number of such lattices, called the Siegel mass formula. In this...

We study a set of yield stress fluid flows in channels with geometric non-uniformities, motivated by theoretical aspects and industrial applications. Methodology is primarily computational and we try to analytically investigate as much as possible...

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}...

In this talk, we will introduce a deterministic malaria model for determining the drug administration protocol that leads to the smallest first malaria episodes during the wet season. To explore the effects of administering the malaria drug on...

Much of the progress in applied mechanics and applied math has resulted from the gradual accumulation of knowledge and understanding through contributions by a community of researchers. However, occasionally a single paper contains fundamentally new...
