Clifford-Fischer theory applied to certain groups associated with symplectic, unitary and Thompson groups.
The character table of a finite group is a very powerful tool to study the groups and to prove many results. Any finite group is either simple or has a normal subgroup and hence will be of extension type. The classification ...
On convection and flow in porous media with cross-diffusion.
In this thesis we studied convection and cross-diffusion effects in porous media. Fluid flow in different flow geometries was investigated and the equations for momentum, heat and mass transfer transformed into a system ...
Aspects of distance measures in graphs.
In this thesis we investigate bounds on distance measures, namely, Steiner diameter and radius, in terms of other graph parameters. The thesis consists of four chapters. In Chapter 1, we define the most significant terms ...
Combined impulse control and optimal stopping in insurance and interest rate theory.
In this thesis, we consider the problem of portfolio optimization for an insurance company with transactional costs. Our aim is to examine the interplay between insurance and interest rate. We consider a corporation, such ...
Measurement and modelling of households' demand and access to basic water in relation to the rapidly increasing household numbers in South Africa.
Service delivery in post-apartheid South Africa has become a topical issue both in the academia and the political arena . The rise of social movements, the xenophobic tensions of May 2008 and protest actions could be ...
A numerical study of entropy generation, heat and mass transfer in boundary layer flows.
This study lies at the interface between mathematical modelling of fluid flows and numerical methods for differential equations. It is an investigation, through modelling techniques, of entropy generation in Newtonian ...
Approximation methods for solutions of some nonlinear problems in Banach spaces.

Lie group analysis of exotic options.
Exotic options are derivatives which have features that makes them more complex than vanilla traded products. Thus, finding their fair value is not always an easy task. We look at a particular example of the exotic options ...
