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, ...
On the similarities in properties of essential numerical range and Davis-Wielandt shell of Hilbert space operators
(International Journal of Innovative Research and Advanced Studies (IJIRAS), 2017-07)
Let be an operator on an infinite dimensional Hilbert space . Denote the essential numerical range of the operator by and the Davis-Wielandt shell of the operator by . We review the properties of the essential numerical ...
Characterization of norm inequalities for elementary operators
(International Journal of Modern Science and Technology, 2017)
Studies on the norms of the elementary operators on JB* -algebras Prime C * -algebras, Calkin algebras and standard operator algebras has been considered. In this paper, we characterize norm inequalities for Jordan elementary ...
