    The structural organization of a giant mafic dyke swarm, the Okavango complex, in the northern Karoo Large Igneous Province (LIP) of NE Botswana is detailed. This N1108E-oriented dyke swarm extends for 1500 km with a ...
  • Mapeo, R.B.M.; Ramokate, L.V.; Corfu, F.; Davis, D.W.; Kampunzu, A.B. (Elsevier Ltd. www.elsevier.com/locate/jafrearsci, 2006)

    We study semi-parallel lightlike hypersurfaces of an indefinite Kenmotsu manifold, tangent to the structure vector field. Some Theorems on parallel and semi-parallel vector field, geodesibility of lightlike hypersurfaces ...
  • Robdera, Mangatiana A. (Science Domian International, www.sciencedomain.org, June 24, 2014)
    We introduce the notion of summable bases that naturally generalizes the notion of unconditional sequence bases for Banach spaces. We shall be particularly interested in some classical results on sequences and series in ...
  • Robdera, Mangatiana A.; Kagiso, Dintle (Scientific Research, http://www.scirp.org, November, 2013)
    The Lebesgue-Nikodým Theorem states that for a Lebesgue measure λ:Σ〖⊂2〗^Ω→[0,∞) an additive set function F:Σ→R which is λ-absolutely continuous is the integral of a Lebegsue integrable a measurable function ...
  • Robdera, Mangatiana A. (Pushpa Publishing House, www.pphmj.com, October, 2010)
    In this note, we propose a more efficient approach to the definition of the integral of Banach-valued functions that enables us to give an improved version of the Orlicz-Pettis theorem for integrals.
