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. -
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 ... -
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.
