Thesis
Oloo, J. O. Collapses of linearly decaying three-dimensional perturbations in homogeneous and weakly stratified boundary layers. (Thesis). Keele University. https://keele-repository.worktribe.com/output/418970

The physical mechanisms of why an orderly laminar flow suddenly becomes turbulent are still poorly understood, despite more than a century of incessant efforts. The thesis puts forward a radically new approach to understanding of the fundamental chal...

Abelian fixed point free endomorphisms and the Yang-Baxter equation (2020)
Journal Article
Koch, A., Stordy, L., & Truman, P. J. (2020). Abelian fixed point free endomorphisms and the Yang-Baxter equation

We obtain a simple family of solutions to the set-theoretic Yang-Baxter equation, one which depends only on considering special endomorphisms of a finite group. We show how such an endomorphism gives rise to two non-degenerate solutions to the Yang-B... Read More about Abelian fixed point free endomorphisms and the Yang-Baxter equation.

A Simple 3D-Only Evolutionary Bipedal System with Albatross Morphology for Increased Performance (2020)
