  • Compactness in pointfree topology 
    Twala, Nduduzo Tedius (2022)
    Our discussion starts with the study of convergence and clustering of filters initiated in pointfree setting by Hong, and then characterize compact and almost compact frames in terms of these filters. We consider the ...

    The aim of this research was to examine the extent to which algebra content was taught to Grade 9 mathematics learners in four schools within a specific education district in Gauteng province, South Africa. This qualitative ...
  • On yosida frames and related frames 
    Matabane, Mogalatjane Edward (2012)
    Topological structures called Yosida frames and related algebraic frames are studied in the realm of Pointfree Topology. It is shown that in algebraic frames regular elements are those for which compact elements are rather ...
