    • Semiperfect CFPF rings. 

      Francis, Donald Nicholas. (1987)
      The Wedderburn-Artin Theorem (1927) characterised semisimple Artinian rings as finite direct products of matrix rings over division rings. In attempting to generalise Wedderburn's theorem, the natural starting point will ...
    • Some aspects of semirings of functions. 

      Nsayi, Jissy Nsonde. (2014-02-25)
      A well known fact of classical analysis is that the Stone- Cech compacti cation of a Tychono space is achieved as the structure space of the commutative unitary ring of real valued continuous functions de ned on it. An ...
    • Some models of relativistic radiating stars. 

      Mahlatji, Matsimele Ngwalodi . (2012)
      In this dissertation we study radiating stars in strong gravitational elds. We generate new classes of exact solutions to the Einstein eld equations and the boundary condition applicable to radiating relativistic stars. ...
    • Spanning trees : eigenvalues, special numbers, and the tree-cover ratios, asymptotes and areas of graphs. 

      Adewusi, Fadekemi Janet. (2014)
      This dissertation deals with spanning trees associated with graphs. The number of spanning trees of a graph can be found by considering the eigenvalues of the Laplacian matrix associated with that graph. Special classes ...
    • Spherically symmetric solutions in relativistic astrophysics. 

      John, Anslyn James. (2002)
      In this thesis we study classes of static spherically symmetric spacetimes admitting a perfect fluid source, electromagnetic fields and anisotropic pressures. Our intention is to generate exact solutions that model the ...
    • Using artefacts to support an embodied approach to learning trigonometry : a case study of grade 10 learners. 

      Niranjan, Caresse. (2013)
      The purpose of this study was to explore the role of artefacts (manipulatives) in the teaching and learning of trigonometric ratios in grade 10. The study focused on how the use of manipulatives aided learners’ mathematical ...
