    • On compact power operators whose norms are eigenvalues 

      Owino, Julia (Strathmore University, 2017)
      The class of compact operators is fundamental in operator theory. Characterization of compact operators acting on different spaces has been fascinating to many Mathematicians. Many properties such as boundedness, completeness, ...
    • On Compactness of similarity orbits of norm-attainable, Operators 

      Mogotu, P. O.; Okelo, N.B.; Ongati, Omolo (Strathmore University, 2019-08)
      The notion of compactness plays an important role in analysis. It has been extensively discussed on both metric and topological spaces. Various properties of compactness have been proved under the underlying spaces. ...
    • On joint essential maximal numerical ranges 

      Omoke, Priscah Mogotu (Strathmore University, 2017)
      The study of numerical range of an operator has been an area of intense research. The motivation for the development arose from the classical theory of quadratic forms. It forms a very important aspect in functional analysis, ...
    • On Joule heating triggered by oscillating surface 

      Nyamai, Benjamin (Strathmore University, 2017)
      This study aims at investigating the amount of Joule heating which occurs as a result of oscillating surface in an electrically conducting fluid exposed to a uniform magnetic field. Joule heating increases the thermal ...
    • On Magnetohydrodynamic(MHD) boundary layer flow of nanofluids past a porous flat plate 

      Njane , Winifred Mutuku -; Makinde, O.D. Prof.
      Paper presented at Strathmore International Mathematics Research Conference on July 23 - 27, 2012
    • On one nonclassical problem for the Laplace equation 

      Danilkina, Olga (Strathmore University, 2017)
      Nonlocal problems received special attention over the past few decades due to efficient descriptions of various phenomena in physics, chemistry and engineering in cases when data from the boundary of the process or initial ...
    • On self adjoint norm-attainable operators 

      Okelo, Benard (Strathmore University, 2017)
      In this paper we present the theory of norm-attainability for Hilbert space operators. In particular, we characterize self-adjointedness of the norm-attainable operators. We also outline the relationship between ...
    • On the Banach algebra numerical range 

      Kaubya, Francis; Agure, John Ogonji; Emenyu, John (Strathmore University, 2017)
      Let A denote a unital Banach algebra and SA denote its unit sphere. It was proved by F. F. Bonsalland J. Duncan that when the Banach algebra is unital, the algebra numerical rangeis identical to a subset of itself. Basing ...

    • On the Eigenvalue problem involving the Robin p (x)-Lap1acian 

      Lubega, Mohammad; Karuhanga, Martin (Strathmore University, 2019-08)
      A nonlinear eigenvalue problem with Robin boundary conditions on a bounded domain is investigated. The existence of a sequence of non-negative eigenvalues is established using the Ljusternik-Shnirelmann principle. Using ...
    • On the European logistic-type option pricing with jump diffusion 

      Oduor, Brian; Mulambula, Adanje (Strathmore University, 2019-08)
      Black- Scholes formed the foundation of option pricing. However, some of its assumptions like constant volatility and interest among others are practically impossible to implement hence other option pricing models have ...
