Mathematical modeling of HIV/aids co-infection With tuberculosis and pneumonia incorporating protection
(Maseno University, 2016)
The synergistic relationship between HIV/AIDS and respiratory infections, such as tu-
berculosis(TB) and pneumonia not only results in high mortality rates but is also a source
of economic burden borne by many nations ...
Certain properties of essential Numerical ranges of bounded Operators on banach spaces
(Maseno University, 2018)
Abstract
The numerical range of an operator on a Hilbert space has been extensively
researched on. The concept of numerical range of an operator goes back
as early as 1918 when Toeplitz defined it as the field of values ...
Zero Divisor Graphs of Classes of Completely Primary Finite Rings of Maximal Prime Power Characteristic
(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 ...
On the Essential Numerical Range
(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 ...
Match Analysis of HIV/AIDS Model With Reference to Kenya
(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 ...
Mathematical model for non-linear stock price adjustment
(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
(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
(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 ...
