• Linearization of an abstract convexity space 

      Yong, Sin (1978)
      Axiomatic convexity space, introduced by Kay and Womble [22] , will be the main topic discussed in this thesis. An axiomatic convexity space (X,C), which is domain finite and has regular straight segments, is called a ...
    • Metrization and sigma bases 

      Hansen , Lawrence David (1969)
      In this thesis, we use the concept of sigma base to study the metrizability of various topological spaces. Chapter 1 is devoted to the definition of basic terms, a proof of Urysohn's Metrization Theorem, and an introduction ...
