A multiplicative analogue of Schnirelmann's theorem
Aled Walker
Apr 16, 2019
The classical theorem of Schnirelmann states that the primes are an additive basis for the integers. In this paper, we consider the analogous multiplicative setting of the cyclic group (ℤ/𝑞ℤ)× and prove a similar result. For...
Additive energy and the metric Poissonian property
Let $A$ be a set of natural numbers. Recent work has suggested a strong link
between the additive energy of $A$ (the number of solutions to $a_1 + a_2 = a_3
+ a_4$ with $a_i \in A$) and the metric Poissonian property, which is...
Bicycle helmet wearing is associated with closer overtaking by drivers
There is a body of research on how driver behaviour might change in response to bicyclists’ appearance. In 2007, Walker published a study suggesting motorists drove closer on average when passing a bicyclist if the rider wore a...

Mixing time of random walk on dynamical random cluster
We study the mixing time of a random walker who moves inside a dynamical random cluster model on the d-dimensional torus of side-length n. In this model, edges switch at rate μ between open and closed, following a Glauber...

Strong Roots 2 Climate Change Adaptation Project Report
N C Nash, Rhodri Thomas, Paul Egan, Liz Court, Jim Poole, Lydia Beaman, Aled Vaughan-Owen
Jan 01, 0001
Climate change is clearly a global issue, but also one that manifests itself locally. The global dimension requires an understanding of the world’s climate (i.e. physical science). Local adaptation requires a knowledge of...
Random walks on dynamical percolation
We study the behavior of random walk on dynamical percolation. In this model, the edges of a graph \(G\) are either open or closed and refresh their status at rate \(\mu \) while at the same time a random walker moves on \(G\)...
Faraday pilot-wave dynamics
A millimetric droplet bouncing on the surface of a vibrating fluid bath can self-propel by virtue of a resonant interaction with its own wave field. This system represents the first known example of a pilot-wave system of the...
