Dissertation in mathematics is an individual project where students investigate and study a specific area of mathematical research or an application of advanced mathematical techniques and write a report on their findings. When writing a dissertation in mathematics, you will learn to understand complex mathematical texts, work on open-ended problems, and communicate mathematical reasoning and ideas clearly. In your dissertation, you need to report what was previously known on a particular topic and contribute to some field of mathematics.

A Masters dissertation can be either expository that explains some results that are already known or research-based that includes a new theorem. A PhD dissertation in mathematics is based on original mathematical research and includes at least one previously unknown substantial theorem. Keep in mind that quality is more important than quantity.

Mathematical sentences contain notations, figures, and equations that are difficult to type if you use a typical word-processing program. If you are going to type your dissertation in mathematics yourself, you should dedicate a certain amount of time to become familiar with this software.

Typically, good papers are thoroughly rewritten at least once or twice and the key sections often require 3 to 5 major revisions. A dissertation in mathematics reports results of your investigation and should meet the following standards:. The first step in writing a dissertation in mathematics is choosing a topic. The dissertation project typically relates to the research interests of your supervisor so you should speak to members of the staff about possible dissertation topics and find out who works in the areas that you are interested in.

Dissertations in mathematics typically give an extended analysis of a particular topic and report on a research project or study. A dissertation commonly consists of multiple chapters:. A dissertation in mathematics is based on independent mathematical research which differs from most researches in other fields of knowledge.

Typically, it takes about a year and a half of hard work reading papers and attacking different math problems before you find one that you can prove. So first, you need to choose an advisor, select a topic, and work hard on your research reading papers, making conjectures, and proving lemmas. While reading, you should analyze examples, and memorize important vocabulary.

You may need a couple of years to prove your theorem and you never know if you are following the right or the wrong path for a proof until you actually find it. When you start writing your dissertation, you should provide definitions for terms and notations that you will use throughout the paper so that your readers can understand your work. The best way to do it is to provide explanations of the key terms in the introduction section.

Your introduction should also clearly describe the problem and put it into the context. When writing the main chapters of your dissertation, you should split lengthy proofs in several steps or several lemmas, taking care of the logical flow. When writing a proof, you must start with the hypothesis and use other mathematical truths such as definitions, axioms, computations or theorems to arrive at the desired conclusion.

Write your proof like a manual in a natural step-by-step order. You need to provide all logical steps but there is no need to explain obvious arguments. You should provide step-by-step explanations in full sentences. When you finish a long argument, you should summarize it.

Given one or more polynomials in several indeterminates, what do their set of common zeros look like? Curves and surfaces are typical examples. This topic examines the basic theory of such objects. It can be done both at an elementary level and at a more sophisticated level. The material of the Term 7 course on Ring Theory would be handy. Semple, J. Cubic curves in the plane may have a singular point or be non-singular.

The non-singular points on a cubic form an abelian group, which leads to many remarkable properties such as the theory of the nine associated points, from which many other results can be deduced. A non-singular elliptic cubic is one of the most beautiful structures in mathematics.

In defining a vector space, the scalars belong to a field, which can also be finite, such as the integers modulo a prime. Many combinatorial problems reduce to the study of geometrical configurations, which in turn can be analysed in a geometry over a finite field. Hirschfeld, J.

Mathematical epidemiology is the study of the spread of diseases, in space and time, with the objective to trace factors that are responsible for, or contribute to, their occurrence []. Mathematical models are frequently used in real applications e. Many such models assume that individuals can either be susceptible S , infected and infectious I , and recovered or removed R.

In these basic but fundamental models, susceptible or healthy individuals can become infected upon contact with infected individuals and these can then recover and become susceptible again or become immune or removed with no further impact on the epidemic.

In this context the following projects are proposed:. We will consider a pairwise model that allows to capturing epidemic dynamics on a network that evolves in time [8]. Namely, the network has a fixed set of edges that can become deactivated and re-activated, as a possible response by individuals who try to avoid infection. The aim of this project is to formulate an SIS susceptible-infected-susceptible pairwise model and to analyse this both analytically and numerically in order to determine the epidemic threshold, disease prevalence and to characterise the interaction between disease and network dynamics.

The project will involve model formulation and the derivation of differential equations to construct the pairwise model, as well as analytical and numerical analysis of the resulting model. This project will focus on various types of stochastic epidemic models [7, 9] based on the classic SIS susceptible-infected-susceptible and SIR susceptible-infected-removed models. In this project we aim to derive exact models by exploring the symmetries of the network in term of the networks automorphism group.

We will start from simple toy networks, with extension to more realistic networks, and we will formulate ordinary differential equation models that are related to the Kolmogorov forward equations corresponding to a continuous time Markov Chain. The project will involve model formulation, numerical solution to the formulated model, as well as comparison to simulation results. The application of inference methods maximum likelihood and Bayesian methods will be explored in the context of deterministic and stochastic epidemic models.

The susceptible-infected-susceptible SIS and susceptible-infected-recovered SIR epidemic models will be considered using pairwise or other mean-field models,as well as the full stochastic counterpart of the explicit stochastic epidemic simulation on networks. Possible questions include: a can we recover the network or its properties from epidemic data, b can we identify the source of infection from infection data, and c how can these methods be extended to real-world networks and spreading processes such as tweets on twitter and spread of memes.

Excellent introductory reading for this topic can be found in []. We will consider a number of real-world networks, such as the network of global cargo ship movements [14] or other technological or social networks, and apply tools from network sciences to uncover their properties in terms of degree distribution, clustering, community structure, path length [15,16] and by simulating various spreading processes on them.

We will also aim to combine network analysis with the processes unfolding on these networks to better understand how such networks emerged and continue to evolve. Roberts, M. Trends Microbiol.

From the prototypical example of steel to modern day shape-memory alloys, materials undergoing martensitic transformations exhibit remarkable properties and are used in a wide range of applications, e.

The properties of these materials, such as the toughness of steel or Nitinol being able to remember its original shape, are related to what happens at small length scales and the ability of these materials to form complex microstructures. Hence, understanding how microstructures form and how they give rise to these properties is key, not only to find new applications, but also to design new materials.

A mathematical model, developed primarily in the last 30 years [1,2,3], views microstructures as minimizers of an energy associated to the material and has been very successful in explaining many observables. In fact, it has been successful even in contributing to the design of new smart materials which exhibit enhanced reversibility and low hysteresis, properties which are crucial in applications.

In this project, we will review the mathematical theory - based on nonlinear elasticity and the calculus of variations - and how it has been able to give rise to new materials with improved properties. Depending upon preferences, the project can be more or less technical. Key words: microstructure, energy minimisation, elasticity, calculus of variations, non-convex variational problems.

A priori estimates coming from the PDE itself typically allow for convergence of the approximation to be established in some weak topology which, however, does not suffice to pass to the limit under a nonlinear quantity. This loss of continuity with respect to the weak topology is a great obstacle in nonlinear problems.

This project aims to identify and analyse models of coupled elements, which are connected with time-delays.

These types of systems arise in various different disciplines, such as engineering, physics, biology etc. The interesting feature where the current state of the system depends on the state of the system some time ago makes such models much more realistic and leads to various potential scenarios of dynamical behaviour. The models in this project will be analysed analytically to understand their stability properties and find critical time delays as well as numerically using MATLAB.

Geometric constructs such as curves, surfaces, and more generally immersed manifolds, are traditionally thought as static objects lying in a surrounding space. In this project we view them instead as moving within the surrounding space. While Differential Geometry, which on of the basis of Geometric Motions, is a mature theory, the study of Geometric Motions themselves has only really picked-up in the late seventies of the past century.

This is quite surprising given the huge importance that geometric motions play in applications which range from phase transition to crystal growth and from fluid dynamics to image processing. Here, following the so-called classical approach, we learn first about some basic differential geometric tools such as the mean and Gaussian curvature of surfaces in usual 3-dimensional space.

We then use these tools to explore a fundamental model of geometric motions: the Mean Curvature Flow. We review the properties of this motion and some of its generalisations. We look at the use of this motion in applications such as phase transition.

This project has the potential to extend into a research direction, depending on the students will and ability to pursue this. Extra references will be given in that case. One way of performing this extension would be to implement computer code simulating geometric motions and analysing the algorithms. Gurtin, Morton E. Oxford Mathematical Monographs.

Stochastic Differential Equations SDEs have become a fundamental tool in many applications ranging from environmental risk management to mechanical failure control and from neurobiology to financial analysis. While the need for effective numerical solutions of SDEs, which are differential equations with a probabilistic uncertain data, closed form solutions are seldom available.

Prerequisites for this direction are some knowledge of probability, stochastic processes, partial differential equations, measure and integration and functional analysis. In particular, we learn about pseudorandom numbers, Monte-Carlo methods, filtering and the interpretation of those numbers that our computer produces.

Although not a strict prerequisite, some knowledge of probability, ordinary differential equations and their numerical solution will be useful. We study these models both from a theoretical point of view connecting to their Physics and we run simulations using computational techniques for stochastic differential equations. The application field will be emphasised and must be clearly to the student's liking. Although very interesting as a topic, I prefer not to deal with financial applications.

This research seeks to study open topical problems in experimental sciences biochemistry, biomedical engineering, genetics, cell biology, etc.

By analysing experimental observations, the challenge is to derive new mathematical models from first principles that will describe both qualitatively and quantitatively these observations. In most cases, numerical approximate solutions to the analytical solutions will be sought.

A candidate researcher should be one who is fascinated with the idea of applying mathematics to non-standard research questions emanating from experimental sciences. The precise topic will depend on the strength of the candidate. Furthermore, good computing skills are an added advantage. In summary, the research entails identification of an appropriate research topic in collaboration with the supervisor s , literature review, mathematical modelling, analysis of the models, numerical computations, solution visualisations, model validation and refinement.

Finally, a project report will be written ideally using! If the research results are ground-breaking, article publication is the ultimate goal.

Its achievements are among the most profound and most fascinating in Quantum Theory, e.

Melgaard, G. II, , Handb. Reed, M. Academic Press, Inc. Quantum Mechanics QM has its origin in an effort to understand the properties of atoms and molecules. When we proceed to a molecule, however, the QM problem cannot be solved in its full generality. In particular, we cannot determine the solution i.

This problem corresponds to finding the minimum of the spectrum of! For systems involving a few say today six or seven electrons, a direct Galerkin discretization is possible, which is known as Full CI in Computational Chemistry. For larger systems, with! The approximations can be divided into wavefunction methods and density functional theory DFT.

A magnetic field has two effects on a system of electrons: i it tends to align their spins, and ii it alters their translational motion. The first effect appears when one adds a term of the form! Within the numerical practice, one approach is to apply a perturbation method to compute the variations of the characteristic parameters of, say, a molecule, with respect to the outside perturbation.

It is interesting to go beyond and consider the full minimization problem of the perturbed energy. In Hartree-Fock theory, one only takes into account the effect ii , whereas in nonrelativistic DFT it is common to include the spin-dependent term and to ignore ii and to study the minimization of the resulting nonlinear functional, which depends upon two densities , one for spin "up" electrons and the other for spin "down" electrons. Each density satisfies a normalisation constraint which can be interpreted as the total number of spin "up" or "down" electrons.

The proposed project concerns the above-mentioned problems within the context of DFT in the presence of an external magnetic field. More specifically, molecular Kohn-Sham KS models, which turned DFT into a useful tool for doing calculations, are studied for the following settings:. Resonances play an important role in Chemistry and Molecular Physics.

They appear in many dynamical processes, e. The aim of the project is carry out a rigorous mathematical study on the use of Complex Absorbing Potentials CAP to compute resonances in Quantum Dynamics.
