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 ...

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 local minimum and orthogonality of normal derivations in Cp-classes 

Owino, B. O.; Okelo, Bernad N.; Ongati, Naftali O. (G.I publications, 2017-02)
The present paper gives some results on local minimum and orthogonality of normal derivations in Cp-Classes. We employ some techniques for normal derivations due to Mecheri, Hacene, Bounkhel and Anderson. Let CpCp be normal, ...
