The study of the asymptotic behaviour of the summatory function of the number of divisors of shifted primes was initiated by Titchmarsh, who used the generalised Riemann hypothesis to establish a main term and remainder for the sum of tau(p-a) for p...

Leslie Hogben is the Dio Lewis Holl Chair in Applied Mathematics and Professor of Mathematics at Iowa State University, and the Associate Director for Diversity of the American Institute of Mathematics. She received her B.A. from Swarthmore College...

A wide variety of physical and biological systems can be described as continuum limits of interacting particles. Many of these problems are gradient flows and their dynamics are governed by a monotonically decreasing interaction energy that is often...

Individually and collectively, cells are organized systems with many interacting parts. Mathematical models allow us to infer behaviour at one level of organization from information at another level. In this talk, I will share two biological...

Multiphase flows are commonly encountered in nature and industrial applications. In nature for example, debris and ash from volcanic eruptions is a potential hazard to aviation, and the suspension of sand and dust poses serious consequences for...

We present a mathematical model of the core mechanism responsible for the regulation of polarized growth dynamics by the small GTPase Cdc42. The model is based on the competition of growth zones of Cdc42 localized at the cell tips for a common...

In open pit mining, one must dig a pit, that is, excavate upper layers of ground to reach valuable minerals. The walls of the pit must satisfy some geomechanical constraints (maximum slope constraints) so as not to collapse. The ultimate pit limits...

We characterize the intrinsic complexity of a set S in a metric space W by the least dimension N (epsilon) of a linear space V ⊂ W that can approximate S to an epsilon error. We show a scaling law for N (epsilon) for high frequency wave fields in...

Well, it's not really a construction yet -- it's more like a template for constructions. It's a way to take many copies of one tetravalent graph B, the 'base graph', and identify each edge-midpoint with one other according to another graph C, the...
