Certain properties of normaloid operators
(JOOUST, 6/24/2015)
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.
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 ...
