    • Spherically symmetric cosmological solutions. 

      Govender, Jagathesan. (1996)
      This thesis examines the role of shear in inhomogeneous spherically symmetric spacetimes in the field of general relativity. The Einstein field equations are derived for a perfect fluid source in comoving coordinates. ...
    • Stellar structure and accretion in gravitating systems. 

      John, Anslyn James. (2012)
      In this thesis we study classes of static spherically symmetric solutions to the Einstein and Einstein–Maxwell equations that may be used to model the interior of compact stars. We also study the spherical accretion of ...
    • Stratification and domination in graphs. 

      Maritz, J. E. (2006)
      In a recent manuscript (Stratification and domination in graphs. Discrete Math. 272 (2003), 171-185) a new mathematical framework for studying domination is presented. It is shown that the domination number and many ...
    • The thermal Sunyaev-Zel'dovich effect as a probe of cluster physics and cosmology. 

      Warne, Ryan Russell. (2010)
      The universe is a complex environment playing host to a plethora of macroscopic and microscopic processes. Understanding the interplay and evolution of such processes will help to shed light on the properties and evolution ...
