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 ...
New conditions for counteractivity of normality operators
(2017-08)
An interesting area in operator theory is the study of norm inequalities for Hilbert space operators. Many
mathematicians have worked on this subject, for example in [2, 3 and 5]. On the other hand, contractive
and ...
New conditions for contractivity of normaloid operators
(Journal of Global Research in Mathematical Archives, 2017-08)
In this paper we establish new conditions for contractivity of normaloid operators. We employ some results for contractivity due to Furuta, Nakomoto, Arandelovic and Dragomir. A particular generalization is also given.
Norm bounds for contractive normality operators
(2017-08)
In this paper we establish the upper and lower norm estimates of contractive normaloid operators using inner product,
Schwarz inequality for non-negative real numbers and some operator inequalities.
