  • Fifth order two-stage explicit Runge-Kutta-Nystrom method for the direct integration of second order ordinary differential equations 

    Okunuga, S.A.; Sofoluwe, A.B.; Ehigie, J.O.; Akanbi, M.A. (Academic Journals, 2012)
    In this paper a direct integration of second-order Ordinary Differential Equations (ODEs) of the form using the Explicit Runge-Kutta-Nystrom method with higher derivatives is presented. Various numerical schemes are derived ...
  • A model for control of HIV/AIDS with parental care 

    Abiodun, Gbenga Jacob; Marcus, Nizar; Okosun, Kazeem Oare; Witbooi, Peter J. (World Scientific Publishing, 2013)
    In this study we investigate the HIV/AIDS epidemic in a population which experiences a significant flow of immigrants. We derive and analyze a mathematical model that describes the dynamics of HIV infection among the ...
  • Multiplication of Crowns 

    Witbooi, Peter J. (Instituto de Matematica de Bahia Blanca (INMABB-CONICET), 2013)
    It is known that the only nite topological spaces that are H-spaces are the discrete spaces. For a nite poset which is weakly equivalent to an H-space, a generalized multiplication may be found after suitable ...
  • Numerical treatment of Kap's equation using a class of fourth order method 

    Akanbi, M.A.; Okunuga, S.A.; Sofoluwe, A.B. (Academic Journals, 2011)
    Kap's equation is a stiff initial value problem. This paper deals with the treatment of Kap's equation using a class of 4th order explicit Runge-Kutta method. Numerical computation was carried out using Microsoft Visual ...
  • An SEIRS epidemic model with stochastic transmission 

    Witbooi, Peter J. (Springer, 2017)
    For an SEIRS epidemic model with stochastic perturbations on transmission from the susceptible class to the latent and infectious classes, we prove the existence of global positive solutions. For sufficiently small values ...
