On quasisimilarity, almost similarity and metric equivalence of some operators in hilbert spaces
(School of mathematics, 2012-08)In the first chapter we give a brief introduction on some of the developments of the equivalence relations came about. We also define some of the notations and terminologies that will be used in this work. The second ... -
On Reducibility And Quasireducibility Of Operators In Hilbert Spaces
(University of Nairobi, 2015)In this dissertation, we study invariant, reducing and hyp erinvariant subspaces and how they play a key role in the study of reducibility and quasireducibility of op erators. We also consider some equivalence relations and ... -
On Ricci Solitons as Quasi-einstein Metrics
(university of nairobi, 2019)This thesis is the key to good understanding of di erential geometry with para- Kenmotsu and Lorentzian Para- Sasakian structure and it is organized as follows. In chapter one, the preliminaries and de nitions are ... -
On some aspects of spectral theory of Operarors in Hilbert spaces

On Some Classes Of Operators On Hilbert Space
(University of NairobiSchool of mathematics, 1982)In this project, H will d8note a Hilbert space with inner projuct denoted by < ,7 and T, A, B, X etc. will denote operators (i.e. bounded, linear trans- formations) on a Hilbert space H into itself or into another ... -
On some properties of solvability of polynomials by radicals
(School of mathematics, 2011-08)The first section provides a brief history of advancements in solvability by radicals. In chapter 1, we begin by introducing a few elementary concepts ill field theory and the key items needed in solvability by radicals. ... -
On some transforms of linear operators in a hilbert space
(University of Nairobi, Kenya, 2012)Let B (H) be algebra of all bounded linear operator in a complex separable Hilbert space. For an operator T E B (H). let II en = I T I ''u I T I ''. r en = I T I u, C (T) = (T _ iI) (T+ iI)-! be the Aluthge transform, ... -
On Stock Market Dynamics and Options Pricing Based on Garch and Regime Switching Models
(University of Nairobi, 2022)The understanding of the linkage between stock returns, volatility and trading volume is paramount since it provides insights into the financial markets’ micro-structure. The available literature reveals insufficient ... -
On the application of credibility theory and GLMS
(University of NairobiSchool of Mathematics, 2013)Premiums are payable to an insurance company for a cover against a certain risk. Credibility models are actuarial tools to distribute premiums fairly among a heterogeneous group of policyholders. The problem is usually ... -
On The Capture-Recapture Methods Of Estimating Population Size
(University of NairobiSchool of mathematics,, 1991)This dissertation 1S an attempt capture-recapture models estimation of to study the closed population size. Where possible, the assumptions underlying various models have been discussed ... -
On the Cartesian and Direct Sum Decomposition of Operators in Hilbert Spaces
(University of Nairobi, 2023)In this project,we study the Cartesian and the direct sumdecomposition of operators in Hilbert Spaces with a view of determining the properties of their components. We first show that an arbitrary operator... -
On the classification of semisimple Lie algebras
(School of Mathematics, University of Nairobi, 2010)Lie algebra over a field F (F= [; lis a vector space Lover F equipped with a skew symmetric bilinear operation called the Lie bracket, which satisfied the Jacobi identity. Lie algebras, have Jordan decomposition into ... -

On the construction of mixed poisson distributions
(University of Nairobi, Kenya, 2012)Mixed poisson distributions are very significant in modeling non - homogeneous populations, for instance in Actuarial applications for modeling total claims in insurance. In this work the concentration is mainly on the ... -

On The Geometric Properties Of The Numerical Ranges Of Bounded Linear Operators
(School of Mathemetics, 2013)This study is on the characterization of the numerical ranges of a bounded linear operator T on a Hilbert space H. In case of a bounded linear operator, the closure of the numerical range apart from including the spectrum ... -
On the identification of an optimum flood frequency model
(1986)Although a number of nonparametric analysis have appeared in the literature, traditional flood frequency analysis has been approached primarily as a problem in parametric statistical inference. Peak annual streamflow ... -
On The Monthly Mean Lower Tropospheric Circulation And The An0i1alous Circulation During The 1961/62 Floods In East Africa
(Department of Meteorology, 1983)The period between September 1961 and January 1962 saw the most severe floods experienced in East Africa (Kenya, Uganda, Tanzania) this century. Flooded rivers damaged both road and rail communications, agricultural ...
