Norm estimates for convexoid operators
(JOOUST, 2015-06-24)Hilbert space operators are important in formulation of principles of quantum mechanics and also in other fields of applied sciences. These operators include normal operators, hyponormal operators, normaloid operators, ... -
Norm of a derivation and hyponormal operators
(Int J Math Anal, 2010)We characterize when the norm of inner derivation on a norm ideal equals that on the quotient algebra. We further investigate norms of inner derivations implemented by normal and hyponormal operators on norm ... -
Norm Properties of S -Universal Operators
(Communications in Advanced Mathematical Sciences, 2020)We investigate the norm properties of a generalized derivation on a norm ideal J in B(H), the algebra of bounded linear operators on a Hilbert space H. Specifically, we extend the concept of S−universality from the inner ... -
Norms of Derivations Implemented by S-Universal Operators
(International Journal of Mathematical Analysis, 2011)Let H be a complex Hilbert space and B(H) the algebra of all bounded linear operators on H. For A, B ∈ B(H), we define inner derivations implemented by A,B respectively on B(H) by ΔA(X) = AX−XA, ΔB(X) = BX−XB and a ... -
Norms of elementary operators
(Maseno University, 2015)Properties of elementary operators have been investigated in the recent past under a variety of aspects. Their norms have been a subject of interest for research in operator theory. Specifically, deriving a formula to ... -

Norms of elementary operators.
(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 ... -
Norms of generalized derivations on norm ideals
(Maseno University, 2019)The norms of inner and generalized derivations on different kinds of algebras have been determined. However, the norms of their restrictions to norm ideals have not been fully explored. For instance, the concept of ... -
Norms of Inner Derivations on Norm ideals
(Int. Journal of Math. Analysis, 2010)Let B(H) be the algebra of bounded linear operators on a Hilbert space H and J be a norm ideal in B(H). We investigate the relationship between the diameter of the numerical range of an operator A ∈ B(H) and the norm ... -
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 ... -
A note on momentum and energy conservation in dynamics under arbitrary forces in classical Newtonian and relativistic mechanics
(Research gate, 2018)In teaching mechanics course to first year undergraduate students, I have come across a simple, but very important, gap in the formulation of the principle of conservation of momentum and energy in the dynamics of a body ... -
NOTIONS OF CONTINUITY FOR FINITE RANK MAPS IN THE SPACE OF NORMAL OPERATORS
(2020)We show that a natural extension of a continuous finite rank operator to an arbitrary Hilbert space is continuous. We also give sufficient conditions to calculate delta- epsilon numbers in all the domains of T. In addition, we ... -

Novel biomarkers with promising benefits for diagnosis of cervical neoplasia: a systematic review
(BioMed Central, 2020)Background: Cervical cancer screening is slowly transitioning from Pappanicolaou cytologic screening to primary Visual Inspection with Acetic Acid (VIA) or HPV testing as an effort to enhance early detection and ... -
A novel ED-based sexual assault centre in western Kenya: description of patients and analysis of treatment patterns
(BMJ Publishing Group Ltd and the British Association for Accident & Emergency Medicine, 2011-11-01)he aim of this study was to establish the feasibility of a Kenyan emergency department (ED)-based sexual assault centre; and to improve knowledge of the characteristics of sexual assault in the region. -
Novel Long Retentive Posaconazole Ophthalmic Suspension
(Pharmaceutical Science and Technology, 2020-02-14)Ophthalmic formulations are not completely available for eliciting therapeutic action because of various reasons such as rapid tear drainage, blinking of eye, lower residence time and lower cul de sac volume. Ophthalmic ... -
Novel sources of resistance to blast disease in finger millet
(2020)Finger millet (Eleusine coracana (L.) Gaertn. subsp. coracana) is the most important millet in eastern Africa and perhaps the oldest domesticated cereal grain in Africa. One of the major factors limiting finger millet ... -
NPK (S) fertilizer use in commercially cultivated clone BBK 35 in different tea growing regions of Kenya: I. Experimental design and initial soil chemical properties.
(Tea Research Foundation of Kenya, 2008)An experiment was set up in five sites by superimposing on commercially grown plantations consisting of one popular tea cultivar, clone BBK 35 at Timbilil estate, Kericho; Changoi Estate, lower Kericho; Magura-Kipkebe ... -
