  1. Lamron <em>ℓ</em>-groups

    Lamron <em>ℓ</em>-groups

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    The article introduces a new class of lattice-ordered groups. An ℓ-group G is lamron if Min(G)−1 is a Hausdorff topological space, where Min(G)−1 is the space of all minimal prime subgroups of G endowed with the inverse topology. It will...
  2. Seasonal Fluctuations and Diversity of Bark and Wood-boring Beetles in Lowland Forest: Implications for management Practices

    Item type: Journal Article • Journal: South African Forestry Journal
    The phenology and diversity of wood-living beetles attacking Cedrela mexicana, Khaya nyasica and Milicia excelsa were observed for one year with weekly window-flight-trap collections. A total of 150 species (10 known to be common pests of timber) were collected, most...
  3. Particulate organic matter, soil texture and mineralogy relations in some Eastern Cape ecotopes in South Africa

    Particulate organic matter, soil texture and mineralogy relations in some Eastern Cape ecotopes in South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Contrasting reports have been given on the relationships between soil texture, mineralogy and particulate organic matter (POM). The objective of this study was to determine the effects of soil texture and mineralogy on aggregate POM in several ecotopes in the...
  4. THE KRALL POLYNOMIALS: A NEW CLASS OF ORTHOGONAL POLYNOMIALS

    THE KRALL POLYNOMIALS: A NEW CLASS OF ORTHOGONAL POLYNOMIALS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    A new set of orthogonal polynomials is found that are solutions to a sixth order formally self adjoint differential equation. These polynomials are shown to generalize the Legendre and Legendre type polynomials. We also show that these polynomials satisfy many...
  5. ON EPIDENSE SUBCATEGORIES OF TOPOLOGICAL CATEGORIES

    ON EPIDENSE SUBCATEGORIES OF TOPOLOGICAL CATEGORIES

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Dense subcategories were introduced by S. Mardešić for an inverse system approach to (categorical) shape theory.
  6. CARTESIAN CLOSEDNESS AND THE MCNEILLE COMPLETION OF AN INITIALLY STRUCTURED CATEGORY

    CARTESIAN CLOSEDNESS AND THE MCNEILLE COMPLETION OF AN INITIALLY STRUCTURED CATEGORY

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    An adaptation of a theorem by Herrlich [5] shows that every initially structured category A can be fully embedded in a topological category AC, which is, in fact, a MacNeille completion of A. It is then shown that A is...
  7. AN APPLICATION OF A NEW THEOREM ON ORTHOGONAL POLYNOMIALS AND DIFFERENTIAL EQUATIONS

    AN APPLICATION OF A NEW THEOREM ON ORTHOGONAL POLYNOMIALS AND DIFFERENTIAL EQUATIONS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Recently this author proved that if an OPS satisfies a differential equation of the form
  8. ON A-WEAKLY MPACT OPERATORS

    ON A-WEAKLY MPACT OPERATORS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    The aim of this note is to study the A-weakly compact operators using an arbitrary space ideal A. Since F ⊂ A the n-weakly compact operators of [9] are particular A-weakly compact operators.
  9. CARTESIAN CLOSED TOPOLOGICAL HULLS AS INJECTIVE HULLS

    CARTESIAN CLOSED TOPOLOGICAL HULLS AS INJECTIVE HULLS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    It is shown that (concretely) Cartesian closed topological hulls can be characterized as injective hulls in a rather natural setting. The characterization of locale hulls as injective hulls in the category of (meet-) semilattices by Bruns & Lakser and Born...
  10. WALLMAN REMAINDERS OF REGULAR SPACES

    WALLMAN REMAINDERS OF REGULAR SPACES

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    This paper shows that the only Hausdorff spaces which can occur as Wallman remainders of Regular spaces are themselves completely regular. This is in contrast to the previously known result that any T1 space can occur as a Wallman remainder.
