    • 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 ...
    • 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 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 ...
    • 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 ...
    • 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 ...
    • Mathematical model for non-linear stock price adjustment 

      OMONDI, Lawrence Onyango (Maseno university, 2010)
      The field of financial mathematics has drawn a lot of interest from both practitioners and academicians since the derivation of Black- Scholes model of 1970s. :Ihe celebrated option pricing formula, the so-called Black- ...
    • Non-parametric regression estimation of a finite Population total in the presence of Heteroscedasticity 

      INGUTIA, K. Celestine (Maseno university, 2010)
      Non parametric regression provides computationally intensive estimation.of unknown finite population quantities. Such estimation is usually more flexible and robust than inferences tied to design - probabilities (in ...
    • Efficiencies of reinforced bib and augmented· Block designs in sugarcane test families’ vs Controls experiments 

      MAINA, Peter Wachira (Maseno university, 2010)
      The designs used for experimentation generally require making all the possible paired comparisons among the treatments but in plant breeding selection programmes the comparison of interest is usually a subset of all the ...
    • 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. ...
    • 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 ...
    • Deterministic modelling of tuberculosis and Hiv/aids 

      ODUNDO, Francis Okello (Maseno university, 2010)
      The human immunodeficiency virus (HIV) pandemic presents ~ massive challenge to the control of recurrent diseases like tuberculosis (TB) at all levels. Tuberculosis is also one of the most common causes of morbidity and ...
    • 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 ...
    • 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 ...
    • Match Analysis of HIV/AIDS Model With Reference to Kenya 

      OKONGO, Mark Onyango (Maseno University, 2011)
