Omphalos, miracles, and Occam's razor
(University of Botswana, www.ub.bw, 2018-12-14)Philip Gosse’s Omphalos (1857), which attempted to reconcile Genesis with science by proposing that the pre-Adamite stage of the world existed only as a Platonic idea, has usually been criticized as violating Occam’s razor ... -
On almost sure behavior of stable subordinators over rapidly increasing sequences
(Society for Industrial and Applied Mathematics, http://epubs.siam.org, 2006)Let (X(t), t ≥ (0) with X(0) = 0 be a stable subordinator with index 0 < α < 1 and let (tk) be an increasing sequence such that tk+1/tk → ∞ as k → ∞. Let (at) be a positive nondecreasing function of t such that a(t)/t ... -
On cartesian nets and fubini-tonelli type theorem
(International Journal of Applied Physics and Mathematics, http://www.ijapm.org/, 2017-04)The notion of Cartesian net is introduced in order to provide an appropriate setting for the notion of double limit for directed functions defined on Cartesian products of spaces. As an application, we obtain extensions ... -
On natural characterizations of tensor integrability
(Science Domain International, http://www.sciencedomain.org/, 2015-05-04)We revisit the definition of the tensor integrability introduced in [1], and prove some useful characterizations that provide a foundation for studying relevant properties to the integration theory. As applications, we ... -
On non-metric covering lemmas and extended Lebesgue-differentiation theorem
(Science Domain International;http://www.sciencedomain.org, 2015-03-28)We give a non-metric version of the Besicovitch Covering Lemma and an extension of the Lebesgue-Differentiation Theorem into the setting of the integration theory of vector valued functions. -
On semi-parallel lightlike hypersurfaces of indefinite Kenmotsu manifolds
(Birkhäuser Basel. http://www.springerlink.com/content/107580/?p=1930c3cc1de944feae211b785b3b42a4&pi=0, 2009)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 ... -
On size function topology and fixed point theorems
(International Scientific Publications and Consulting Services, http://www.ispacs.com/about.php, 2017-06)In this paper, we introduce and study a metric-like (non-necessarily metric) topology that is weaker than the original topology of a given topological space. The results are used to provide more useful and more general ... -
On summable bases in Banach spaces
(Science Domian International, www.sciencedomain.org, 2014-06-24)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 ... -
On the differentiability of vector valued additive set functions
(Scientific Research, http://www.scirp.org, 2013-11)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 ... -
On the Orlicz-Pettis theorem for integrals
(Pushpa Publishing House, www.pphmj.com, 2010-10)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. -

On the Riesz representation theorem and integral operators
(NISC (Pty) Ltd, http://www.nisc.co.za/, 2015-12-14)We present a Riesz representation theorem in the setting of extended integration theory as introduced in [6]. The result is used to obtain boundedness theorems for integral operators in the more general setting of spaces ... -
On the status of subject markers in African languages
(Joongwon Linguistic Society of Korea, http://submission.jwl.or.kr/sobis/jwl.jsp, 2017)This paper discusses subject markers in African languages, noting that whereas the grammatical functions of these morphemes are fairly clear; their status as affixes or clitics is not. The unclear status of subject markers ... -
On the subspace problem for Quasi-normed spaces
(ScienceDomain International; www.sciencedomain.org, 2016-07-02)A definitive positive answer to the so-called proper subspace problem (a.k.a. the atomic space problem) for quasi-normed spaces is given: every infinite dimensional quasi-normed space has a proper closed infinite-dimensional ... -
One body playing many parts-Ie Betjouana, el Negro, and il Bosquimano
(University of Botswana, Research and Development Unit/http://digital.lib.msu.edu/projects/africanjournals/browse.cfm?colid=12, 2002)This article talks about how the body of El Negro was stolen from southern Africa and how it was kept as an exhibit in a museum in Spain. Two French taxidermists stole the body later known as El Negro from a grave beyond ... -
One step forward, two steps back: a critical analysis of Anglican and Roman Catholic bilateral relations from a theological perspective
(University of Botswana, www.ub.bw, 2018-12-14)This paper is a critical examination of Anglican-Roman Catholic bilateral relations from a theological perspective. The main argument of the paper is that while the Anglican and Roman Catholic Churches consider themselves ... -
