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 Norm Preserving conditions for Local Automorphisms of Commutative Banach Algebras
Kangogo, Willy (JOOUST, 2017)Most studies on preserver problems have been on linear preserver prob¬lems (LPPs) in matrix theory. It is known that local derivations of Von Neumann algebras are continuous linear maps, which coincide with some derivation ... -
Properties of Spectrally Bounded Compact Elementary Operators
Kangogo, Willy; Okelo, Nyaare Benard; Ongati, Omolo (DOI: 10.47443/cm.2021.0012, 2021-03-31)Spectrally bounded compact elementary operators on dense irreducible subalgebras of C ∗ -algebras are characterized. Also, it is shown that left multiplications, right multiplications, generalized derivations and basic ...
