Conditions for Positivity of Operators in Non-unital C*-algebras
(International Journal of Mathematical Analysis, 1/9/2015)In this paper, we present results on the necessary and sufficient condi-tions for positivity of operators in non-unital C*- algebras -
Fixed Points Approximation for Non Expansive Operators in Hilbert Spaces
(Int. J. Open Problems Compt. Math, 2/2/2021)Approximations of fixed points have been done in different space and classes. However, characterizations in norm attainable classes remain interesting. This paper discusses approximation of nonexpansive operators in Hilbert ... -
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, ...
