#### Applications of embedding theory in higher dimensional general relativity.

(2014-04-22)

The study of embeddings is applicable and signicant to higher dimensional theories of
our universe, high-energy physics and classical general relativity. In this thesis we investigate
local and global isometric ...

#### Age structured models of mathematical epidemiology.

(2014-11-21)

We consider a mathematical model which describes the dynamics for the spread of a directly
transmitted disease in an isolated population with age structure, in an invariant habitat, where
all ...

#### Optimisation of the population Monte Carlo algorithm : application to cosmology.

(2015-09-04)

In this thesis we study the Population Monte Carlo (PMC) algorithm and utilise simulations to
improve the efficiency of the algorithm by optimising the algorithm parameters. We then ap
ply these optimisation results to ...

#### Models in isotropic coordinates with equation of state.

(2015-09-04)

In this thesis we consider spacetimes which are static and spherically symmetric related
to the Einstein and Einstein-Maxwell system of equations in isotropic coordinates. We
study both neutral and charged matter ...

#### Exact models of compact stars with equations of state.

(2015-01-05)

We study exact solutions to the Einstein-Maxwell system of equations and relate them to compact
objects. It is well known that there are substantial analytic difficulties in the modelling of
self-gravitating, static fluid ...

#### Group theoretic approach to heat conducting gravitating systems.

(2015-01-07)

We study shear-free heat conducting spherically symmetric gravitating
fluids defined in four
and higher dimensional spacetimes. We analyse models that are both uncharged and charged
via the pressure isotropy condition ...

#### Applications of Lie symmetries to gravitating fluids.

(2011)

This thesis is concerned with the application of Lie's group theoretic method
to the Einstein field equations in order to find new exact solutions. We analyse
the nonlinear partial differential equation which arises ...

#### Computational study of high order numerical schemes for fluid-structure interaction in gas dynamics.

(2013-12-17)

Solving the fluid-structure interaction (FSI) problems is particularly challenging. This is because the coupling of the fluid and structure may require different solvers in different points of the solution domain, and with ...

#### Fischer Clifford matrices and character tables of certain groups associated with simple groups O+10(2) [the simple orthogonal group of dimension 10 over GF (2)], HS and Ly.

(2011)

The character table of any finite group provides a considerable amount of information about a group and the use of character tables is of great importance in Mathematics and Physical Sciences. Most of the maximal subgroups ...

#### New models for quark stars with charge and anisotropy.

(2014)

We find new classes of exact solutions for the Einstein-Maxwell field equations. The
solutions are obtained by considering charged anisotropic matter with a linear equation
of state consistent with quark stars. The field ...
