On a generalized q-numerical Range
(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
(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
(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
(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 ...
Approximations of ruin probabilities under financial constraints.
(Maseno University, 2022)
This thesis studies the approximate ruin probabilities under financial constraints which in- clude the rate of inflation, constant interest rate, and taxation. When the surplus falls below zero, the insurance company is ...
Mathematical modeling of Dual protection and art Adherence for a high risk HIV Population
(Maseno University, 2023)
The spread of HIV/AIDS remains a major concern to public health enthusiasts
world over. In spite of interventions such as medical male circumcision,
condom use, treatment using Antiretroviral Therapy (ART), as
well as ...
