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 ...
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
