    • Norms of elementary operators 

      KING'ANG'I, Denis Arnold Njue (Maseno University, 2015)
      Properties of elementary operators have been investigated in the recent past under a variety of aspects. Their norms have been a subject of interest for research in operator theory. Specifically, deriving a formula to ...

    • Norms of elementary operators. 

      RUTO, Peter Kiptoo (Maseno university, 2010)
      The norm of an elementary operator has been investigated over long period by several mathematician under various special circumstances. Timoney working on algebra of bounded linear operators on Hilbert spaces, established ...
    • Norms of tensor products and elementary Operators 

      ODERO, Beatrice Adhiamb (Maseno university, 2009)
      In this thesis, we determine the norm of a two-sided symmetric operator in an algebra. More precisely, .we investigate the lower bound of the operator using the injective tensor norm. Further, we determine the norm of ...
    • Numerical solution of Korteweg-de vries equation 

      ONAM, Joel Otieno (Maseno university, 2008)
      The Kotteweg-de Vrr-es(KdV)is a mathematical model of waves on shallow water surfaces. The mathematical theory behind the KdV equation is rich and interesting, and, in the broad sense, is a topic of active mathematical ...
    • Numerical Solutions of Burgers Equation Using Hybrid Methods 

      OBIERO, Ngutu Tom Kenneth (Maseno University, 2016)
      Research on Burgers equation: u_t + 〖uu〗_x = 〖αu〗_xx which is a second order nonlinear partial differential equation is gaining interest for its application and mathematics itself. It arises in model studies of turbulence ...
    • On a generalized q-numerical Range 

      Musundi, Sammy Wabomba (Maseno university, 2008)
      We 'consider numerical ranges of a bounded linear operator on complex Hilbert spaces. Many properties of the classical numerical range are known. We investigate the properties of the q-numerical range in relation to ...
    • On completely bounded Operators 

      AMBOGO, David Otieno (2010)
      Calculating norms of matrices when the entries are not constants is the first problem tackled in this thesis. We have considered the space of matrices with entries from the algebra of bounded linear operators and ...
    • On completely positive maps 

      Ndong'a, Julia Owino (Maseno University, 2015)
      Completely positive maps is an important field due to its significance, application and mathematics itself. While discussing the properties of the positive maps, researchers have questioned whether the properties of the ...
    • On norms of a derivation 

      BONYO, Job Otieno (Maseno university, 2010)
      The study of derivations still remains an area of interest to mathematicians today. Of special attention has been the study of norms of inner derivations. Most of the work in this area is based on Stampfli's result of ...
    • On norms of elementary operators 

      NYAARE , Benard Okelo (2009)
      The study of elementary operators has been of great interest to many mathematicians for the past two decades. Of special interest has been to determine the norms of these operators. The norm problem for elementary operators ...
    • On the Essential Numerical Range 

      OWEGO, Dancun Okeso (Maseno University, 2013)
      The convexity. closure and compactness of the numerical range among other properties constitute a considerable literature in operator theory. The properties of the essential numerical range and how they are related to ...
    • On the numerical ranges and Spectra of normal operators 

      KISENGO, Kibeu Samuel (Maseno university, 2010)
      The study of numerical ranges and spectra has been of great interest to many mathematicians in the past decades. In this study, we have continued to look at the numerical ranges and spectra of operators .on a Hilbert space. ...
    • Operation of mutation on Polar quivers 

      OYENGO, Michael Obiero Michael Obiero (Maseno university, 2009)
      In recent times, there has been a lot of interest in the study of quivers, both by mathematicians and theoretical physicists. We introduce a new concept of polar quivers and their mutation. The idea of polar quivers arises ...
    • Zero Divisor Graphs of Classes of Completely Primary Finite Rings of Maximal Prime Power Characteristic 

      WALWENDA, Shadrack Adero (Maseno University, 2017)
      It is well known that in a finite ring R, every element is either a zero divisor or a unit. The classification of finite rings is not fully settled. Different studies have generated interesting results on certain classes ...
