Norms and numerical radii inequalities for ( , ) - normal transaloid operators
Nyaluke, Wesley K.; Okelo, Bernad N.; Ongati, Naftali O. (JOOUST, 6/24/2015)The studies on Hilbert spaces for the last decade has been of great interest to many mathematicians and researchers, especially on operator inequalities related to operator norms and numerical radii for a family of bounded ... -
Norms of derivation associated with idempotents and unitary operators
Moses, Ouma O.; Ongati, Naftali O.; Okelo, Bernad N. (6/24/2015)The study of operators has continued to attract the attention of many researchers. Of special interest are the calculations of norms of these operators. Johnson Stampfli wrote a paper on the norms of derivation on algebra ... -
On norm preserving conditions for local automorphisms of commutative banach algebras
Kangogo, Willy; Okelo, Bernad N.; Ongati, Naftali O. (JOOUST, 6/24/2015)The history of commutative algebra first appeared in 1890 by David Hilbert which was then followed by Banach spaces in 1924 since localization reduces many problems of geometric special case into commutative algebra problems ... -
On shift of mindset: the importance of change of mindset in helping students get better at getting better in mathematics
34; Owiti, Dickson S.O.; Ongati, Naftali O. (JOOUST, 6/24/2015)That mathematics is important in enhancing creativity, innovativeness and technological development is undisputable. Kenya like any other African country is endowed with reach human resource yet lesscompetitive ...
