Further remarks on unitary equivalence of some classes of operators in Hilbert spaces
(University of Nairobi, 2020)
n this paper we investigate results on unitary equivalence of operators that include n-binormal, skew
binormal and n-power-hyponormal operators acting on complex Hilbert space H. AMS subject classification ...
On unitary equivalence of some classes of operators in Hilbert spaces
(University of Nairobi, 2020)
Abstract
It is a well-known result in op erator theory that whenever two op erators are similar then they have equal
sp ectra even though they do not have to belong to the same class of op erators. However ...

Two new flavonoids from Dracaena usambarensis Engl.
(University of Nairobi, 2020)
Investigations of the root extract of Dracaena usambarensis Engl. for anticancer principles led to the characterization of one new homoisoflavonoid, (3S)-3,4ʹ,5,6-tetrahydroxy-7-methoxyhomoisoflavanone (1) and a new ...
