  • 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 ...
  • On norms of elementary operators

  • 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 ...
  • Mathematical modelling of flood Wave: a case study of Budalang'i Flood plain basin in Busia county, Kenya 

    MUSINDAYI, Stephen Miheso (Maseno university, 2022)
    Flooding is a worldwide problem with more adverse e ects in developing countries. In Kenya, severe ooding is experienced on the lower tributaries of Lake Victoria, mainly Budalang'i area. This is indicated in the ...
  • 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 ...
  • 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 ...
  • 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- ...
  • 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 ...
  • Match Analysis of HIV/AIDS Model With Reference to Kenya 

    OKONGO, Mark Onyango (Maseno University, 2011)
    Epidemiology models are used to combine complex data from various sources in order to study equally complex outcomes. The first simple HIV/AIDS epidemic model was by Anderson in 1986. Since then a lot has been done in ...
  • 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 ...
  • Mathematical Model Incorporating Screening of Immigrants as A Control Against The Spread of Ebola 

    KW AMBOKA, Lilian (Maseno University, 2017)
    Ebola Disease Outbreak (EVD) is an acute and often fatal disease in humans and nonhuman primates (monkeys, gorillas and chimpanzees). The disease is caused by infection with a virus of the family of Filoviridae, genus ...
  • 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 ...
