Ergodic Theory and Dynamical Systems

(See also Demi Allen, Robert MacKay, James Robinson, and David Wood)

Adam Epstein offers projects in Complex and Arithmetic Dynamical Systems, for example:

Arithmetic Questions in Holomorphic Dynamics: Consider the polynomials F_n(c) = p_c o ... o p_c(0) (n-fold self-composition) where p_c(z) = z^2 + c. It is known that all roots of F_n(c) are simple. The polynomial F_n splits into factors, some of which arise as F_m for smaller m dividing n: when such factors are divided out, the resulting polynomials are conjectured to be irreducible. Questions of this nature arise for other interesting families of rational maps, and little is known in general. Well-organised computer experimentation would be a good start. This would be an appropriate project for a student who has taken, or will be taking Algebraic Number Theory (or Galois Theory). Familiarity with basics from Complex Analysis and Dynamical Systems would also be useful.

Dimension is a way to quantify the size of sets with complex structure. Typically it is very difficult to compute accurately. This project relates to sets which have a certain dynamical flavour to their construction (e.g. Cantor sets, Snowflakes, Julia sets, etc.) and to the techniques available in this context for more accurate estimation of the dimension; or even explicit values in some cases. The project will involve numerical computations with Matlab/Fortran/C.

Fluid Dynamics

(See also Dwight Barkley, Colm Connaughton, Tobias Grafke and the Applied Analysis and Computational Mathematics sections above)

Radu Cimpeanu supervises projects at the intersection between mathematical modelling, asymptotic analysis, solutions for ordinary/partial differential equations and high performance computing (including computational linear algebra and large scale system solvers). Specific topics in fluid mechanics include interfacial flows (modelling, analysis, simulation and applications of drops, bubbles and liquid films), rheological flows (from chocolate to de-icing fluids) and novel mathematical models for the cultivated meat industry. Some projects are likely to include multi-physics aspects such as acoustics, heat transfer and electromagnetism. From a mathematical standpoint, there are exciting opportunities to combine classical (continuum) modelling with discrete and data scientific streams, as well as integrating approaches such as control theory or hybrid modelling into areas previously unexplored with such tools. More generally, work on any of the above will likely involve a mixture of analytical and computational techniques (which can be tailored depending on your own interests and what skillset you wish to develop), as well as the interplay between them.

James Sprittles offers projects on the mathematical modelling and computational simulation of fluid mechanical phenomena, particularly those driven by complex interfacial effects which are prevalent in the emerging field of micro/nanofluidics. These microflows often require new modelling approaches, involving both continuum and particle-based methods, coupled to efficient computational techniques and are currently an area of intensive research interest. Possible projects include (but are not limited to):

Gas Dynamics in Free-Surface Flows: Thin films of gas often have a huge influence on the dynamics of liquid volumes, e.g. when drops impact solids, but at present are lacking an accurate theoretical description (in fact, often their influence is ignored). The problem is that their dimension is such that classical continuum mechanics fails and kinetic theory governed by the Boltzmann equation is required. This project will involve developing new models for this class of flows, with particular attention applied to the coupling of kinetic theory with continuum mechanics, and exploiting scale-separation to make these models computationally tractable.

Universal Behaviour of Drop Formation: The formation of a drop from a column of liquid (as seen from a dripping tap) is a singular flow which, remarkably, is governed by a 'universal' similarity solution (i.e. the final stages of the liquid breaking always look the same). However, recent computational results have revealed, twenty years after the original theory was proposed, that the approach to this solution is not uniform, so that the liquid's surface oscillates in time. This project will involve developing theory and computations to investigate the stability of the similarity solution in order to understand these new surprising results.

Oleg Zaboronski offers a project related to

(see also Charles Elliott and Björn Stinner)

Louise Dyson works on mathematical modelling of biological systems, especially the epidemiology of neglected tropical diseases and the analysis of biological systems in which noise plays an important role.

Matt Keeling offers projects in the areas of Epidemiology,Ecology or Evolution. Epidemiology (the study of infectious diseases and their spread in populations), Ecology (the study of animal/plant populations and their environment), Epidemiology (the study of disease spread and control) and Evolution (the study of the long-term dynamics of populations) present a wide variety of interesting problems that require a mathematical approach. There are a vast number of problems and approaches that could be studied, ranging from model-development, to computer simulation, to statistical analysis. If you've attended (or planning to attend) MA4E7: Population Dynamics, that would be a distinct advantage although not essential. I like to offer projects that show how the mathematical techniques you've learnt can be applied to real questions to obtain useful or meaningful insights. If you're interest, its probably easiest to come and talk with me, and together we can determine a specific project that matches your interests and skills.
Recent projects have included the evolution and competition of influenza strains, diffusion approximations to disease spread on networks, optimal control of spatial epidemics, Nicholson-Bailey lattice models.

Kat Rock is a mathematical epidemiologist interested in population-level disease dynamics. In particular her focus is on transmission of vector-borne (insect-transmitted) infections, infections in low- or middle-income countries, and bringing together dynamic transmission modelling and health economic evaluation. She teaches the MA4M1 “Epidemiology by Example” course and it would be recommended to have taken this and/or “Population Dynamics” (MA4E7) already or alongside an R-project.

Dave Wood would be willing to discuss possible topics given the information below. His main interests for projects include ecological type modelling, investigating systems with symmetry (including but not limited to applications to arthropod locomotion) and applications of mathematics in industry. Systems with symmetry could be theoretical or applied, but would concentrate on using methods from MA3J3 Bifurcations, Catastrophes and Symmetry, so this may interest students who have taken that. The industrial applications could cover a broad range of mathematical disciplines and be a survey of some problems that have already been studied or a look at a new problem involving original research. Ecological modelling I would be happy to consider any suitable application that a student feels passionate about (see below for a couple of past such projects).

Previous titles he has supervised include: “Coupled cell networks, bifurcations and symmetry”, “The effects of tuna fishing on dolphin populations”, “Symmetry in coupled cells and neuronal networks”, “Applications of maths in industry”, “Discrete maths in industry”, “Modelling the Future of the Hawaiian Honeycreeper: An Ecological and Epidemiological problem” (the latter of which led to a successful PhD).

Nigel Burroughs applies mathematical and statistical methods to biological systems. He is primarily interested in understanding the mechanics and mechanisms of cells, in effect how they work and achieve the spectacular range of behaviours that are observed. He uses a combination of model development, mathematical analysis (dynamical systems, perturbation theory), simulation and statistical computation (Markov chain Monte Carlo methods), with both deterministic and stochastic models/systems, although most are stochastic given the fact that cells often show stochastic behaviour. Projects are in the mechanics of cell division, from the duplication and separation of the chromosomes to the mechanical separation of cells into two daughter cells, (1, 2 below), microtubule modelling (3, 4) and cancer modelling (5):

1. Modelling chromosome oscillations. Chromosomes are duplicated but then have to be divided so that each daughter cell gets one and only one copy. This is achieved by 'holding' the pairs at the cell equator until all pairs are in position. Mathematically we can think of this system as two particles in a 1D box connected by a spring and pushed/pulled separately from the ends. The surprising observation is that chromosomes oscillate from side to side across the cell equator. How this occurs is poorly understood, but this is believed to involve a tension sensor that effectively acts as a communication system between the two chromosomes. This project would involve analysis of deterministic and stochastic models of oscillation of paired chromosomes (dynamical systems techniques and simulation), examining different mechanisms of feedback/communication.

2. Statistical computation (Markov chain Monte Carlo, MCMC) analysis of chromosome oscillations. See above (1) for system description. Here you would use our large database of paired chromosome trajectories (1000s of trajectories) to understand the statistical structure of chromosome oscillations, fitting saw-tooth like oscillatory profiles. Experience with MCMC, hidden Markov chains and probability theory is essential.

3. Modelling microtubule bending. Microtubules are biological polymers that polymerise into tubes and exhibit elastic bending properties. Here you will examine models and simulations of microtubule bending in fluid flow and binding of proteins that enhance the curvature.

4. Reverse engineering microtubules. Microtubules are biological polymers; they polymerise into tubes and exhibit what is called dynamical instability, switching from periods of growth to decay. What causes this (stochastic) switching is unknown but likely an emergent property of the microtubule lattice. The idea of this project would be to construct models and an MCMC algorithm to fit those models of lattice dynamics to data to examine the degree to which such data can inform on the underlying processes. Experience with MCMC and probability theory is essential.

5. Cancer evolution. Cancer is a Darwinian process whereby the cell functional pathways are mutated to escape growth control processes. There are multiple control processes, each controlled by a large number of genes. Under Darwinian evolution one predicts that only one mutation is required in each of these groups of genes. You will construct an MCMC algorithm to test this on real data to demonstrate this mutual exclusion prediction.

Prospective students should contact him to discuss further details. [Experience with MCMC means acquaintance with Gibbs and Metropolis-Hastings algorithms and their use in simulating posterior probability distributions. Experience coding an algorithm for a simple problem would be an advantage].

David Rand. His main research interest is Systems Biology, particularly understanding the design principles of regulatory and signalling systems in cells. Prospective students would have to see him to discuss further details.

Potential topics include: cosmological inflation, primordial gravitational waves, large-scale structures and Bayesian methods in cosmology. These projects will involve extensive use of Python. Background knowledge of cosmology or astrophysics, whilst ideal, is not necessary. An ideal student would be someone who is deeply curious about the nature and the origin of the Universe. Further enquiries are welcome.

Roman Kotecky's interests are in discrete mathematics, probability theory, statistical mechanics, mathematical physics. Prospective students would have to see him to discuss further details.

Florian Theil offers project in the area of molecular dynamics which is an active and fast developing field in Applied Mathematics. The objective is to obtain insight into complex molecular systems by means of computer simulations instead of using experimental techniques. Due the high dimensionality the simulations are very costly and consequentially analytical results can provide valuable insights which potentially improve the efficiency of the numerical approaches. The proposed fourth year projects involve the application of tools from Stochastic Analysis and PDE theory to MD systems.

Sam Chow supervises projects in analytic number theory, diophantine equations, and diophantine approximation.

Adam Harper is interested in analytic and probabilistic number theory, and would be willing to supervise projects in these areas. The basic goal is to use methods of analysis (real, complex, Fourier, probability) to understand the distribution of number theoretic objects, like prime numbers. A project would likely involve working through a couple of papers from the (fairly) recent research literature, and trying to understand and synthesise them.

David Loeffler would be willing to supervise projects in various areas of number theory, with possible topics including aspects of p-adic numbers, modular forms, and elliptic curves. See here for a list of previous topics.

Minhyong Kim works on arithmetic geometry, the study of mathematical structures incorporating a mixture of arithmetic and geometric properties. He is also interested in topology and mathematical physics, especially the foundational aspects of quantum field theory. He is willing to supervise a project in any combination of these areas.

Simon Myerson offers projects in analytic number theory and harmonic analysis. You do not need to have taken any particular courses; in particular you do not have to take MA4L6. An interest in number theory and analysis is a must. There are applications to PDEs which would interest students talking MA4J0, although they are unlikely to be the focus of the project. Projects close to algebraic number theory would also be possible if you have an idea in mind.

Samir Siksek is interested in number theory and diophantine equations. Prospective students would have to see him to discuss further details.

Nikos Zygouras: I am working in the area of probability theory and I am interested in studying phenomena that arise from statistical mechanics
of disordered systems (random polymers, motion in random media, stochastic growth etc) and stochastic analysis (SPDEs). I am also interested in the connections to random matrices, algebraic combinatorics, representation theory.
I am happy to supervise fourth year projects focused on two topics
  1. INTEGRABLE PROBABILITY : this is a rather new area within probability which explores remarkable connections between probability and algebraic structures (representation theory, algebraic combinatorics etc). A motivation for this development has been the understanding of the so called Kardar-Parisi-Zhang universality, which governs fluctuations of stochastic growth model (colonies of bacteria, spread of fluid in porous media etc). Remarkably, these fluctuation are not governed by the standard central limit theorem but rather from distributions related to random matrix theory. Some favour on this topic is provided by these notes
  2. SCALING LIMITS OF DISORDERED SYSTEMS AND SPDEs: Stochastic PDEs (SPDEs) have been proposed as continuum scaling limits of statistical mechanics models. However, both the well posedness of the SPDEs and the convergence of the discrete models to these are very challenging problems. The first problem has been recently largely settled below the so-called "critical dimension”) through the theory of Regularity Structures (by Hairer) or Paracontrollled Districutions (by Gubinelli-Imkelle-Perkowski). At the critical dimension things are much more challenging. This project can spin around the above theories, some exploration of critical dimensional statistical mechanics and/or scaling limits. Some flavour of the topic can be obtained in these notes
