Norm estimates for convexoid operators
(JOOUST, 6/24/2015)
Hilbert space operators are important in formulation of principles of quantum mechanics and also in other fields of applied sciences. These operators include normal operators, hyponormal operators, normaloid operators, ...
On local minimum and orthogonality of normal derivations in Cp-classes
(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, ...
Characterization of inner derivations induced by norm-attainable operators
(International Journal of Modern Science and Technology, 2018)
In the present paper, results on characterization of inner derivations in Banach algebras are discussed.Some techniques are employed for derivations due to Mecheri, Hacene, Bounkhel and Anderson. Let H be an infinite ...
