Alternative Energy Sources from Mui Basin in Kitui District, Kenya - A Case of Coal
(Geology Department, Ministry of Energy, KenyaDepartment of Chemistry,University of Nairobi, 2008)Four coal exploration wells were sunk in the Mui Basin area lying in two administrative districts of Kenya, Mwingi and Kitui districts. The average depths sunk ranged between 17 - 135 m. Coal samples encountered were ... -
On A-Commuting Operators
(School of Mathematics, University of Nairobi,, 2012)Two bounded linear operators A and B on a complex Hilbert space are said to ,1.- commute for ,lEe provided that: AB = ABA. In this paper we look for some properties satisfied by the operators A and B so that ,1.= 1. It ... -
On the normality of the products of n-power Quasinormal operators
(Pushpa Publishing House, Allahabad, INDIA,School of Mathematics, University of Nairobi,, 2012)Given any two normal operators A and B on a Hilbert space H, it is known that AB is not normal in general. However, if A and B commute, then AB is also normal. In this account, we investigate some conditions under which ... -

A note on similarity, almost -similarity and equivalence of operators
(School of Mathematics, University of Nairobi,, 2007)The almost- similar and similar relations between operators on finitedimensional Hilbert spaces are investigated. It is shown that almost similar operators share some properties with some other classes of operators. ... -
nth-Aluthge transform of w-Hyponormal Operators
(Pushpa Publishing HouseSchool of Mathematics, University of Nairobi, 2011)In this paper, it is shown the exact location of w-hyponormal operators in a series of operator classes and that; the spectrum of the nth-Aluthge transform of any operator equals that of the operator and for w-hyponormal ... -
