  • Variances of purity within torsion-free Abelian groups 

    Van Ster, Lynnette (University of the Western Cape, 1994)
    In 1921, Prufer introduced the concept of a pure subgroup of an abelian group. This concept, which is applicable only to abelian groups, proved to be a very useful one. Subsequently, this concept has sparked off numerous ...
  • Pairings of binary reflexive relational structures 

    Chishwashwa, Nyumbu (University of the Western Cape, 2007)
    The main purpose of this thesis is to study the interplay between relational structures and topology, and to portray pairings in terms of some finite poset models and order preserving maps. We show the interrelations between ...
  • Analysis and Implementation of a Positivity Preserving Numerical Method for an HIV model 

    Wyngaardt, Jo-Anne (University of the Western Cape, 2007)
    This thesis deals with analysis and implementation of a positivity preserving numerical method for a vaccination model for the transmission dynamics of two HIV subtypes in a given community. The continuous model is analyzed ...
  • Numerical treatment of non-linear singular perturbation problems 

    Shikongo, Albert (University of the Western Cape, 2007)
    This thesis deals with the design and implementation of some novel numerical methods for nonlinear singular perturbations problems (NSPPs). We provide a survey of asymptotic and numerical methods for some NSPPs in past ...
  • Analysis and simulation of nonlinear option pricing problems 

    Tawe, Tarla Divine (University of Western Cape, 2021)
    We present the Black-Scholes Merton partial differential equation (BSMPDE) and its analytical solution. We present the Black-Scholes option pricing model and list some limitations of this model. We also present a nonlinear ...
  • Throughput of UWC students who did at least one semester of third-year Statistics 

    Latief, Abduraghiem (University of the Western Cape, 2005)
    The study explores the completion rates (the number of years a student takes to complete a degree) of graduates at the University of the Western Cape (UWC) in South Africa. The graduates in the study all did at least one ...
  • Codes, graphs and designs related to iterated line graphs of complete graphs 

    Kumwenda, Khumbo (University of the Western Cape, 2011)
    In this thesis, we describe linear codes over prime fields obtained from incidence designs of iterated line graphs of complete graphs Li(Kn) where i = 1,2. In the binary case, results are extended to codes from ...
  • Codes Related to and Derived from Hamming Graphs 

    Muthivhi, Thifhelimbilu Ronald (University of the Western Cape, 2013)
    For integers n, k 2:: 1, and k ~ n, the graph r~has vertices the 2n vectors of lF2 and adjacency defined by two vectors being adjacent if they differ in k coordinate positions. In particular, r~is the classical n-cube, ...
  • Elementary Logic as a Tool in Proving Mathematical Statements 

    May, Bruce Matthew (University of the Western Cape, 2008)
    An analysis of South African school mathematics results indicates that one of the problem areas in the mathematical performance of learners is proof and proving. In an endeavour to improve the mathematical proving ability ...
  • The non-cancellation groups of certain groups which are split extensions of a finite abelian group by a finite rank free abelian group 

    Mkiva, Soga Loyiso Tiyo (University of the Western Cape, 2008)
    The groups we consider in this study belong to the class Xo of all finitely generated groups with finite commutator subgroups. We shall eventually narrow down to the groups of the form T)<lw zn for some nE N and some finite ...

    Chishwashwa, Nyumbu (University of the Western Cape, 2007)
    The main purpose of this thesis is to study the interplay between relational structures and topology, and to portray pairings in terms of some finite poset models and order preserving maps. We show the interrelations between ...
  • The impact of using technology through cooperative learning on learners’ performance on grade 11 circle geometry 

    Shonhiwa, William (University of the Western Cape, 2019-11)
    Euclidean geometry was recently re-introduced as a compulsory topic in the Mathematics Curriculum for learners in the Further Education and Training (FET) band in 2012. The diagnostic analysis reports on the National ...
  • Model theory of algebraically closed fields and the Ax-Grothendieck Theorem 

    Elmwafy, Ahmed Osama Mohamed Sayed Sayed (University of Western Cape, 2020)
    We introduce the concept of an algebraically closed field with emphasis of the basic model-theoretic results concerning the theory of algebraically closed fields. One of these nice results about algebraically closed ...
  • Boundedness and pseudocompactness in pointfree topology 

    Alderaz, Fatma Hussien Shbani (University of Western Cape, 2019)
    This dissertation is a presentation to generalize boundedness and pseudocompactness in pointfree topology. We rst obtain and introduce a boundedness notion for elements of a frame. This is then further inspiration to ...
  • Estimating the cost of deposit insurance for a commercial bank following an optimal investment strategy 

    Matamba, Itani (University of Western Cape, 2020)
    Commercial banks play a dominant role in facilitating the economic growth of a country by acting as an intermediary between the de cit spending unit (borrowers) and the surplus spending unit (lenders). In particular, ...
  • The paradox of enrichment in predator-prey systems 

    Sogoni, Msimelelo (University of Western Cape, 2020)
    In principle, an enrichment of resources in predator-prey systems show prompts destabilisation of a framework, accordingly, falling trophic communication, a phenomenon known to as the \Paradox of Enrichment" [54]. After ...
  • Ultrafilters and Compactification 

    Nxumalo, Mbekezeli Sibahle (UWC, 2020)
    In this thesis, we construct the ultrafilter space of a topological space using ultrafilters as points, study some of its properties and describe a method of generating compactifications through the ultrafilter space. As ...
