  1. Non-proper edge-colouring of graphs and hereditary graph properties

    Non-proper edge-colouring of graphs and hereditary graph properties

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    A graph property is any isomorphism-closed class of graphs. A property is hereditary if, whenever a graph G is in , and H is a subgraph of G, then H is also in . For a hereditary graph property ,...
  2. The partition dimension of circulant graphs

    The partition dimension of circulant graphs

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Let Π = {S1, S2, . . . , Sk} be an ordered partition of the vertex set V (G) of a graph G. The partition representation of a vertex v ∈ V (G) with respect to Π is the...

    Short‐term burning treatments and ecological interactions in the herb layer of false thornveld of the eastern province

    The effects of five years of controlled burning on total floristic composition and on some important species were investigated.

    <em>Citrus tristeza virus</em> cross-protection of ‘Palmer’ navel orange in the Eastern Cape Province of South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Citrus tristeza virus (CTV) is endemic in southern Africa due to the abundance of the citrus brown aphid, To x -optera citricida Kirk., the main insect vector. Virus-free propagation material in the Southern African Citrus Improvement Scheme is pre-inoculated with...
  8. ON A THEOREM OF A.A. LYAPUNOV

    ON A THEOREM OF A.A. LYAPUNOV

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this note we obtain some extensions and an approximation of the Lyapunov convexity theorem by means of the bilinear integration of a set-valued function. The integration is performed successively with respect to a non-atomic, a direct sum and a...
  9. Requests as speech acts in Zulu

    Requests as speech acts in Zulu

    Item type: Journal Article • Journal: South African Journal of African Languages
    In this article I attempt a tentative analysis of requests in Zulu against the background of speech act theory and politeness theory. Data collected by means of discourse completion tests were analysed using the CCSARP methodology and were found to...
